I'm seeing the call to perl_construct() segfault under cygwin. The same code works fine on linux.
Here's the code:
#include <EXTERN.h> #include <perl.h> static PerlInterpreter *my_perl;
int main() {
my_perl = perl_alloc();
perl_construct(my_perl);
printf("Hooray\n");
}The last 10 lines of the backtrace give:
#0 0x10072547 in cygperl5_8_2!Perl_sv_add_arena ()
from /usr/bin/cygperl5_8_2.dll
#1 0x1007dc8b in cygperl5_8_2!Perl_newSVpvn () from /usr/bin/cygperl5_8_2.dll

#9 0x10058488 in cygperl5_8_2!Perl_savesharedpv ()
from /usr/bin/cygperl5_8_2.dll
(More stack frames follow...)
The last few lines of the backtrace appear to be:
#35002 0x10058488 in cygperl5_8_2!Perl_savesharedpv () from /usr/bin/cygperl5_8_2.dll #35003 0x100586b7 in cygperl5_8_2!Perl_vmess () from /usr/bin/cygperl5_8 #35004 0x10059171 in cygperl5_8_2!Perl_vcroak () from /usr/bin/cygperl5_8_2.dll #35005 0x1005963f in cygperl5_8_2!Perl_croak_nocontext () from /usr/bin/cygperl5_8_2.dll #35006 0x1000ae1b in cygperl5_8_2!Perl_malloc () from /usr/bin/cygperl5_8_2.dll #35007 0x1007254c in cygperl5_8_2!Perl_sv_add_arena () from /usr/bin/cygperl5_8_2.dll #35008 0x10079a0e in cygperl5_8_2!Perl_newSV () from /usr/bin/cygperl5_8 #35009 0x100014ac in perl_construct () from /usr/bin/cygperl5_8_2.dll #35010 0x0040108d in cygcrypt-0!crypt () #35011 0x6101c868 in dlerror () from /usr/bin/cygwin1.dll
I've seen a suggestion elsewhere that this is new in 5.8.2, although I can't verify this myself, since I haven't worked out how to downgrade to anything newer than cygwin perl 5.6.
Thanks in advance Luke Diamand
