Bug#333119: gcc-4.0: Segfaulting code generated for gtkboard-0.11pre0
Package: gcc-4.0
Version: 4.0.1-2
Severity: serious
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.
Reproducing:
CFLAGS="-ggdb3 -O" CPPFLAGS= LDFLAGS= ./configure
make
gdb src/gtkboard
(gdb) run

The name of the function makes my suspicions of a compiler bug greater.
Here are the how the dependencies of the compiled gtkboard were satisfied, in
case it is some ABI problem with the loaded libraries...
