following testcase causes gpf on i386.

$ cat exe.c
extern void f() __attribute__((weak,visibility("hidden")));
extern int puts( char const* );
int main()
{
        f ? f() : puts( "f == null, skipped." );
        return 0;
}

$ gcc exe.c -fPIE --save-temps -m32 -O1 && ./a.out
Segmentation fault

this fails on i386 with gcc 3.4.5, 4.0, 4.1 and 4.2 (4.3 not tested).
x86_64 and ppc works fine, so it looks like a ix86 target bug.
