OK, and thanks for confirming! Thus, I'll close the GDB PR. > Additionally adding update_thread_list in gnu_nat.c works for gdb-7.2, > will propose the following patch to the Debian bug report #579834 in > case there will be more releases of the 7.2-series until 7.4 is > released. Either that, or simply continue to use the patch we're currently using (no additional work for the Debian maintainers). The existing patch doesn't do any harm, and can then simply be dropped once Debian is switching to a GDB release that no longer requires the patch -- which is still to be determined. > A few observations when building gdb HEAD: GNU gdb (GDB) > 7.3.50.20110704-cvs though: > > 1) I had to uncomment -Werror when compiling gdb/msg_U.c with Debian > 4.6.1-1+hurd.1 due to the -Wstrict-aliasing flag set by -Wall, see > below: > > msg_U.c: In function 'msg_del_auth': > msg_U.c:505:3: error: dereferencing type-punned pointer will break > strict-aliasing rules [-Werror=strict-aliasing] This issue is known: search for ``werror'' on <http://www.bddebian.com/~hurd-web/open_issues/gdb/>. > 2) When debugging an executable gdb does not find the debugging symbols > for libraries.

I would guess this is not Hurd-specific, but is due to Debian's multiarch changes, and is thus a general problem. Grüße, Thomas
