Ooops, I forgot to save my PKGBUILD before recompile the package. With
-DCOMPILER=CLANG the gbe_bin_generater (btw I think it should spell as
generator...) actually segfault with the following backtrace (and
although the gcc version doesn't segfault, the error message does look
like some sort of memory corruption)
