------- Additional Comments From pcarlini at suse dot de 2005-01-03 16:41 ------- Hi again. Some good news: first, I can confirm that fmttest1.cc does not fail anymore. Morevoer, on x86-64 lfptest fails with gcc3.3 too, therefore something seems wrong in the testcase, not in fpfinal5.patch. While a I dig a little deeper on these issues (and do complete tests on ia64 too), maybe Jerry, you can try to fix lfptest: it would be nice to actually run it to success on the 64-bit machines too... The backtrace is as follows: (gdb) backtrace #0 0x0000002a95b2f10b in __printf_fp () from /lib64/tls/libc.so.6 #1 0x0000002a95b2b416 in vfprintf () from /lib64/tls/libc.so.6 #2 0x0000002a95b46659 in vsprintf () from /lib64/tls/libc.so.6 #3 0x0000002a95b31af8 in sprintf () from /lib64/tls/libc.so.6 #4 0x0000000000401114 in main () at lfptest.cc:58
And, if I print fd.d inside gdb just before the segfault: (gdb) p fd.d $1 = <invalid float value> Are we passing to sprintf a completely crazy third arg?!? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17140
