[Bug c++/39967] New: Ignored static qualifier on a local variable

[sergei_lus at yahoo dot com]

The following (simplified) code originates from peren_c++ (Sec6/7/R06263.r0):

#include <stdio.h>

int ctor_calls;
class A {
        int x;
public:                 // check that was 0 before initialized
        A() {ctor_calls++;}
};

main(){
  for(int i =0; i < 10; i++)
    static A a;

  printf("%d\n", ctor_calls);
}

The output with 3.4.6 port is "0", with 4.3.2 it is "10" (-O0,-O2).

Works for me on i386-darwin and i686-linux-gnu on the trunk, I get the output
of 1 which is the correct value.

With i686-linux-gnu it works also with Debian's GCC 4.3.2.

Target? On x86_64, I can't reproduce your outputs, I'm consistently getting 1,
irrespective of the optimization level and of the release branch (by the way,
only 4.3 and 4.4 are maintained today)

Thanks for prompt response... 

This is an unsupported target, so I guess i will have to narrow it down a bit.
Any suggestions on where to start?

Well, first, spell-out *which* specific target it is. Actually, however, if it
is a completely unsupported target, I'm not even sure it makes sense to keep
the PR open... Other maintainers may know better than me: it's the first time I
triage a PR asking support for a bug of an unsupported target ;)

Please close this issue. I think the real problem is in libc, not in the
compiler. (test passes with -fno-threadsafe-statics). Thank you for support.
