The following program will fail.
gcc -S -O1 -foptimize-sibling-calls bug.c
bug.c:
============================================
#define stdcall __attribute__((__stdcall__))
struct S {
void (stdcall *f)(struct S *);
int i;
};
void stdcall foo(struct S *s)
{
s->i++;
}
void stdcall bar(struct S *s)
{
foo(s);
s->f(s);
}
int main(void)
{
struct S s = { foo, 0 };
bar(&s);
}
============================================
This is what the compiler produces:
bar:
pushl %ebp
movl %esp, %ebp
pushl %ebx
subl $20, %esp
movl 8(%ebp), %ebx
movl %ebx, (%esp)
call foo
subl $4, %esp
movl %ebx, 8(%ebp)
movl -4(%ebp), %ebx
leave
jmp *(%ebx)

I can confirm gcc-4.4.1 errors the same way.
I think stdcall is offender:
My sample is more complicated, but has the same features: stdcall+tailcall.
Produces SIGSEGV for me https://bugs.gentoo.org/show_bug.cgi?id=282189

patch to fix the failure
Sibcalls of any kind should be done through call-clobbered regs only.
This patch fixes the testcase.
Sergei, can you please test it if it fixes your original problem?

This patch fixes for me Dmitry's sample, but does not fix mine. Still SIGSEGVs.
I've managed to
place whole testcase in one file:
$ g++ -O1 -foptimize-sibling-calls -m32 -DCALLTYPE="__attribute__((stdcall))"
main.cc -o show_the_bug
$ ./show_the_bug
Segmentation fault
$ cat main.cc
#define CALLTYPE __attribute__((stdcall))
struct Base {
virtual unsigned long CALLTYPE base_do1(unsigned long, unsigned long)
__attribute__((noinline))
{
return 4;
}
};
static Base bi;
Base * glo_ptr_to_base = &bi;
struct Stuff {
void CALLTYPE do_stuff(unsigned long param1, unsigned long param2)
__attribute__((noinline))
{
if (param1 == 0xFFFFFFFE)
{
return;
}
glo_ptr_to_base->base_do1(param1, param2);
}
};
int
main()
{
Stuff o;
o.do_stuff(1, 32);
return 0;
}

Ah, the same cure should be applied to "*call_value_pop_1" pattern too.
Wait a minute, I'll craft a patch ASAP.
