Modified Files: src/lib/libc/arch/hppa/sys [netbsd-9]: ptrace.S Log Message: Pull up following revision(s) (requested by skrll in ticket #1464): lib/libc/arch/hppa/sys/ptrace.S: revision 1.8 Save and restore %r19 the "linkage table pointer register" across the call to __cerror so if the ptrace syscall fails we can call __cerror again with the correct %r19 value. Do this even though the call of __cerror doesn't go via the PLT because __cerror calls __errno which does. Analysis and fix from Tom Lane in PR port-hppa/56864: hppa: ptrace(2) dumps core when returning an error I changed the location of where %r19 is stored on the stack to follow the ABI.
