Something is very strange:
[EMAIL PROTECTED] thread]$ cat do.c
extern __thread void *foo [];
void
test1 (void)
{
int s;
for (s = 0; s < 2; ++s)
{
foo [s] = &foo[s];
}
}
[EMAIL PROTECTED] thread]$ /export/build/gnu/gcc/build-i686-linux/gcc/xgcc
-B/export/build/gnu/gcc/build-i686-linux/gcc/ -O -S do.c

[EMAIL PROTECTED] thread]$ cat do.c extern __thread void *foo [];

test1 (void)
{

for (s = 0; s < 2U; ++s)

"2U" vs. "2" makes a big difference here.
