32-bit gdb ever worked on 64-bit x86-64 kernel? That's news for me. Yes, I have used it in the not-too-distant past, even to debug multi-threaded programs and to run its testsuite. And I've just verified that it works on FC5/x86_64 with all updates and testing updates as of yesterday. Sorry, false alarm, it's not in glibc, it's in the kernel. sys_ptrace32 regressed in this regard between the FC5 kernel and the rawhide kernel, in that the latter no longer handles PTRACE_[SG]ET_THREAD_AREA. I don't quite see that the handling in the FC5 kernel is entirely correct, but, oddly enough, it appears to work. Anyhow, this makes it a kernel bug, and apparently a regression while at that. Fixed upstream in Nov 2006. |
