--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Full testcase suitable for configure:
extern "C" void abort ();
struct S { ~S () { if (x) abort (); }; int x, y, z; };
void foo (S *p) { *p = S (); }
int main () { S s; s.x = 1; s.y = 2; s.z = 3; foo (&s); if (s.x != 0 || s.y !=
0 || s.z != 0) abort (); }
Given how many places r249234 changed, adding workarounds for the PR33916 GCC
4.2.[0-3] bug might be too pervasive. All 4.2.* compilers from 20061017 to
20080212 are likely broken, unless patched.
