Hi,
when compiling the code below with gcc 4.3 (trunk revision 131293) with -fstrict-aliasing and -Wall -Werror one gets the following compiler output:

gcc-4.3 -o tset test.c -Wall `pkg-config --libs --cflags glib-2.0` -Werror -fstrict-aliasing -O0
cc1: warnings being treated as errors
test.c: In function ‘main’:
test.c:7: error: dereferencing type-punned pointer will break strict-aliasing rules
test.c:8: error: dereferencing type-punned pointer will break strict-aliasing rules

Is this a GLib bug or a gcc one? gcc 4.2 and below didn't complain so either gcc became more correct or more buggy ;)

This is with glib 2.15.0...


test code:

#include <glib.h>

G_LOCK_DEFINE_STATIC (test_lock);

int main()
{
  G_LOCK (test_lock);
  G_UNLOCK (test_lock);
  return 0;
}
