C preprocessor output
Simplified testcase: /* { dg-do compile } */ /* { dg-options "-O2 -g" } */ static void foo (unsigned char x) { unsigned char a[5 + x]; } void bar (void) { foo (80); } Works with both gcc 3.3.4 and 4.0.0. http://gcc.gnu.org/ml/gcc-patches/2004-10/msg01995.html 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). Should be fixed in gcc-3.4.2-6.fc3. |
