Hello, I'm getting a SIGILL, illegal instruction each time I startup my application that is running fine on several other environments. It takes place in startup.pl, before any error_log output is generated. I'm including the back trace below in hopes that someone has a suggestion for me, as I'm quite new to debugging Mod Perl internals. If anyone has any suggestions on what might be the cause or suggest some next steps to diagnose I would be greatly appreciated. -- Thank you.
The particulars of the environment are the following: CentOS 6.2 64Bit Perl Version 5.12.4 (also occurs with 5.14.1) Mod Perl Version: mod_perl-2.0.5 Apache Version: httpd-2.2.19 Backtrace: Program received signal SIGILL, Illegal instruction. 0x000000344ba14c30 in _dl_x86_64_save_sse () from /lib64/ld-linux-x86-64.so.2 Missing separate debuginfos, use: debuginfo-install cyrus-sasl-lib-2.1.23-13.el6.x86_64 expat-2.0.1-9.1.el6.x86_64 glibc-2.12-1.47.el6_2.12.x86_64 keyutils-libs-1.4-3.el6.x86_64 krb5-libs-1.9-22.el6_2.1.x86_64 libaio-0.3.107-10.el6.x86_64 libcom_err-1.41.12-11.el6.x86_64 libselinux-2.0.94-5.2.el6.x86_64 libtool-ltdl-2.2.6-15.5.el6.x86_64 nspr-4.8.9-3.el6_2.x86_64 nss-3.13.1-7.el6_2.x86_64 nss-softokn-freebl-3.12.9-11.el6.x86_64 nss-util-3.13.1-3.el6_2.x86_64 openldap-2.4.23-20.el6.x86_64 openssl-1.0.0-20.el6_2.5.x86_64 oracle-xe-11.2.0-1.0.x86_64 postgresql-libs-8.4.11-1.el6_2.x86_64 zlib-1.2.3-27.el6.x86_64 (gdb) bt #0 0x000000344ba14c30 in _dl_x86_64_save_sse () from /lib64/ld-linux-x86-64.so.2 #1 0x000000344ba0aad8 in _dl_lookup_symbol_x () from /lib64/ld-linux-x86-64.so.2 #2 0x000000344ba0dfb0 in _dl_fixup () from /lib64/ld-linux-x86-64.so.2 #3 0x000000344ba14675 in _dl_runtime_resolve () from /lib64/ld-linux-x86-64.so.2 #4 0x00007fffec494516 in boot_Apache2__Module (my_perl=0x77ab60, cv=0x86bb78) at Module.c:459 #5 0x00007ffff2cdd8ab in Perl_pp_entersub (my_perl=0x77ab60) at pp_hot.c:2885 #6 0x00007ffff2c7590e in Perl_runops_debug (my_perl=0x77ab60) at dump.c:2049 #7 0x00007ffff2baa021 in Perl_call_sv (my_perl=0x77ab60, sv=0x7fd118, flags=14) at perl.c:2605 #8 0x00007ffff2bb6b08 in Perl_call_list (my_perl=0x77ab60, oldscope=11, paramList=0x7a7280) at perl.c:4600 #9 0x00007ffff2b8eaee in S_process_special_blocks (my_perl=0x77ab60, fullname=0x7a2c98 "BEGIN", gv=0x7fd190, cv=0x7fd118) at op.c:5960 #10 0x00007ffff2b8e7ce in Perl_newATTRSUB (my_perl=0x77ab60, floor=275, o=0x804390, proto=0x0, attrs=0x0, block=0x7f5a50) at op.c:5931 #11 0x00007ffff2c1d1ce in Perl_yyparse (my_perl=0x77ab60) at perly.y:567 #12 0x00007ffff2dc2798 in S_doeval (my_perl=0x77ab60, gimme=2, startop=0x0, outside=0x0, seq=241) at pp_ctl.c:3112 #13 0x00007ffff2dc9e0f in Perl_pp_require (my_perl=0x77ab60) at pp_ctl.c:3690 ---Type <return> to continue, or q <return> to quit--- #14 0x00007ffff31cf364 in modperl_pp_require (my_perl=0x77ab60) at modperl_perl_pp.c:70 #15 0x00007ffff2c7590e in Perl_runops_debug (my_perl=0x77ab60) at dump.c:2049 #16 0x00007ffff2baa021 in Perl_call_sv (my_perl=0x77ab60, sv=0x7a7118, flags=14) at perl.c:2605 #17 0x00007ffff2bb6b08 in Perl_call_list (my_perl=0x77ab60, oldscope=5, paramList=0x79c088) at perl.c:4600 #18 0x00007ffff2b8eaee in S_process_special_blocks (my_perl=0x77ab60, fullname=0x7a9918 "BEGIN", gv=0x7c3400, cv=0x7a7118) at op.c:5960 #19 0x00007ffff2b8e7ce in Perl_newATTRSUB (my_perl=0x77ab60, floor=136, o=0x7a2b30, proto=0x0, attrs=0x0, block=0x7f5190) at op.c:5931 #20 0x00007ffff2b837cd in Perl_utilize (my_perl=0x77ab60, aver=1, floor=136, version=0x0, idop=0x80b250, arg=0x0) at op.c:3986 #21 0x00007ffff2c1d5c2 in Perl_yyparse (my_perl=0x77ab60) at perly.y:674 #22 0x00007ffff2dc2798 in S_doeval (my_perl=0x77ab60, gimme=2, startop=0x0, outside=0x0, seq=239) at pp_ctl.c:3112 #23 0x00007ffff2dc9e0f in Perl_pp_require (my_perl=0x77ab60) at pp_ctl.c:3690 #24 0x00007ffff31cf364 in modperl_pp_require (my_perl=0x77ab60) at modperl_perl_pp.c:70 #25 0x00007ffff2c7590e in Perl_runops_debug (my_perl=0x77ab60) at dump.c:2049 #26 0x00007ffff2baafd1 in Perl_eval_sv (my_perl=0x77ab60, sv=0x77eb28, flags=4) at perl.c:2705 #27 0x00007ffff2badb8e in Perl_require_pv (my_perl=0x77ab60, ---Type <return> to continue, or q <return> to quit--- pv=0x737fa0 "/opt/netpos/mg8/run.master/run.8108/conf/startup.pl") at perl.c:2804 #28 0x00007ffff31ae2be in modperl_require_file (my_perl=0x77ab60, pv=0x737fa0 "/opt/netpos/mg8/run.master/run.8108/conf/startup.pl", logfailure=1) at modperl_util.c:48 #29 0x00007ffff319b1b9 in modperl_config_apply_PerlPostConfigRequire ( s=0x6c07c0, scfg=0x712f20, p=0x69e138) at modperl_config.c:455 #30 0x00007ffff3195f6f in modperl_post_config_require (s=0x6c07c0, p=0x69e138) at mod_perl.c:478 #31 0x00007ffff31965ba in modperl_hook_post_config_last (pconf=0x69e138, plog=0x6e0348, ptemp=0x6e2358, s=0x6c07c0) at mod_perl.c:681 #32 0x0000000000437bf9 in ap_run_post_config () #33 0x00000000004245a5 in main ()
