I'm not seeing hurd-dbg / hurd-libs-dbg packages in your repo. Could you please either teach me where to look, or if they're indeed missing, upload them?
Also I can't help but notice that the hurd package (i.e the translator binaries) is still not being built as PIE, unlike basically all the other binaries. This actually helps with debugging for now, but please remember to ensure it does end up as PIE when the system is ready for broader use. /servers/crash-dump-core crashes on the memset () call in hurd:exec/elfcore.c:fetch_thread_fpregset (); the (*fpregs) pointer is NULL. The caller passes fpregs = ¬e.data.pr_fpreg, where note.data is of type struct elf_lwpstatus, defined in hurd:include/sys/procfs.h, whose pr_fpreg field is of type prfpregset_t, which is a typedef to fpregset_t, which was an actual struct on i386, but is a pointer on x86_64. This would've been easier to debug if I had debuginfo :) Sergey
