The following test code incorrectly generates an assertion failure on gcc
mainline and 4.0.1:
#include <assert.h>
struct fbs {
unsigned char uc8;
} fbs1 = {255};
void testfn ( struct fbs *fbs_ptr )
{
if ((fbs_ptr->uc8 != 255) && (fbs_ptr->uc8 != 0))
assert(0);
}
int main (int argc, char *argv[])
{
testfn (&fbs1);
return 0;
}
