Package: gcc-snapshot
Version: 20070422-1
Severity: important
sample code:
=====================================
#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
static int bar(void *p)
{
return (int)(intptr_t)p;
}
static int foo(const void *p)
{
return bar((void *)p);
}
int main(void)
{
printf("%d\n", foo(NULL));
return 0;
}
=====================================
works:
/usr/lib/gcc-snapshot/bin/gcc -o a.o a.c
does not work:
/usr/lib/gcc-snapshot/bin/gcc -O2 -o a.o a.c
a.c: In function 'main':
a.c:12: warning: passing argument 1 of 'bar' discards qualifiers from pointer target type
FWIW under other circumstances I even got an ICE, but I wasn't able to
reduce the testcase, and the code that generated it is not really ..
well open, so I can't give the full file sadly.
