Package: gcc-4.0 Version: 4.0.1-2 Severity: normal gcc seems to generate incorrect code for gtkboard-0.11pre0. Seems to occur with many combinations of flags under -O or greater (as well as without any) and seems to be independent of optimization level. Please note that the source doesnt compile initially (due to a static redeclaration of an extern, that's easy to patch by removing the static qualifier) and also when -O0 is passed (not able to find out the reason for that, so it might be possible that once that is fixed, this bug might manifest for -O0 as well). Please note that there is no problem with gcc-3.3 (even with the static qualifier removal), so this is likely to be a problem with gcc-4.0, rather than the package.
