- Reply-to: gcc-bugzilla at gcc dot gnu dot org
C and C++ programs compiled with gcc 4.1 die with a SIGSEGV in Solaris 9
printstack(). The same programs run successfully when compiled with 4.0.2 and
prior. If this is due to a Solaris bug it would be great if gcc could work
around it.
$ cat t.c && gcc -g t.c && ./a.out || gdb -q a.out
int printstack (int);
int main ()
{
printstack (1);
}
Segmentation Fault (core dumped)
(gdb) run
Starting program: /tmp/a.out
