They likely are using different QEMU versions, and distros may have different patches applied on top. Please provide some more info on what version, what ABI (which executable), what -cpu parameter (if any), etc. you are using. Does a gdb backtrace indicate any QEMU function or is it from translated code? For n64 there were some patches in need of testing, review and fixing. [cc'ing Khansa] For n32 there's signal handling missing. (openSUSE for one ignores the build warning and provides it non the less.) No known issues specific to o32 that I'm aware of, but the two Richards had patches for some instructions. Shouldn't lead to segfaults though.
