------- Comment #2 from aldot at gcc dot gnu dot org  2008-06-09 16:09 -------
Smaller testcase:

extern int dummy(long int *);
void build_range_exp(void)
{
        long int cmp_buf[6] = { L'\0', L'\0', L'\0', L'\0', L'\0', L'\0' };

        if (dummy(cmp_buf)) {
                ;
        }
}


using a smaller cmp_buf (e.g. 5) makes it compile.

Does this work now on the LTO branch?

I can't reproduce this, thus fixed.
