Also it's apparently not in Debian so I won't be able to provide any help. In any case, my guess would be that it tries to map some page RWX and PaX won't allow that. It doesn't expect mmap or mprotect to fail and thus crashes like that (it's a bug in hpasmlited in any case). You might want to look at the sources if you have them, and you might want to run it under strace just to check if that's a mmap/mprotect call failing. Regards, -- Yves-Alexis
