Segfault while building? It is possible on NVIDIA software (but i expect it to work fine on new|recent|updated drivers). On poor AMD hardware the compilation process sometimes takes minutes (usually the first time). This (the compilation big times), i tested, but if Lukas has some free time, i would like to hear from him (e.g., put an exit(0) in the right place). There is an easy test to verify if something related to drivers or optimizations has a bad behavior. If Lukas can try this: export _TYPE=0 \\ "_TYPE") (run John, the way you want). This is easy to try, hurts performance but may "works" on "any" hardware.
