Comment 2 Jakub Jelinek 2004-10-23 17:09:01 UTC
Simplified testcase:
/* { dg-do compile } */
/* { dg-options "-O2 -g" } */

static void
foo (unsigned char x)
  unsigned char a[5 + x];

bar (void)
  foo (80);

Works with both gcc 3.3.4 and 4.0.0.

Comment 3 Jakub Jelinek 2004-10-23 21:58:02 UTC

Not sure how often it triggers though.  It has been introduced on
2004-10-13 in CVS (i.e. only in gcc-3.4.2-6 built on Oct, 18th),
so we probably haven't built enough code to see whether this is
something exceptional or happens more often (in which case we should
put it into FC3).

Comment 4 Jakub Jelinek 2004-10-26 17:29:29 UTC
Should be fixed in gcc-3.4.2-6.fc3.
