Description of problem:

while trying to build libquicktime on rawhide x86_64 (gcc 3.3-12), I receive the
following message:

Comment 3 Jakub Jelinek 2003-07-07 16:12:04 UTC 
Reproduced with:
void bar (int *);

void
foo (int x, int *y)
{
  bar (y + (8 * (x == 1 || x == 3) + 8 * (x == 2) * 16));
}
at -O2 and -O3.
Will debug it soon.
BTW: Did gcc print also something like:

line?
Comment 4 Harald Welte 2003-07-07 17:38:09 UTC 
no, it didn't print such a line.
