Subject: gdb still breaks when debugging threaded programs

Date: Wed, 19 May 1999 09:08:03 -0400

Package: gdb
Version: 4.18-1

  Hi,

  You closed a bug filed by me on this topic recently, but I still can't use
gdb with threaded programs.  Its behavior is improved, though: rather than
hanging when a thread spawns, it sends sigsuspend and returns me to a
(gdb) prompt:

(gdb) run
Starting program: /home/daniel/gaime/gaime-0.5.0/fe-gtk/./gaime 

Program received signal ?, Unknown signal.
0x4054ef2f in sigsuspend () from /lib/libc.so.6
(gdb) 

  I wonder if maybe the threading support wasn't compiled in, since
'info threads' does nothing.

  It may be worth mentioning that RedHat's gdb *does* work with threads and
glibc2.1, so it might be worth looking at their code modifications and compile
flags to see how they got things working. (?)

  Daniel

4.18 does not include the LinuxThreads patch that was in the Debian package
of 4.17; the gdb maintainers have said that it will be integrated in the
next upstream version.

So is Debian going to include the linuxthreads patch before the couple of
years the upstream gdb maintainers spends on each release? I'd prefer not
to wait that long?

Subject: Is it fixed now?

Date: Tue, 26 Oct 1999 13:25:25 +0000 (GMT)

Can you please upgrade to:

- gdb 4.18.19990928-1
- libc6 & libc6-dev 2.1.2-6 (2.1.2-5 is not good enough)

and confirm the problem is fixed?
If not, can you please send an easy to reproduce test case (gdb session +
src code), so I can have a closer look at it.

	Cordialement,

Gdb-5.0 is now packaged, and is supposed to handle multithreaded programs.
(If you're using an other platform that i386, I'd be glad to head succes
reports)
