I'm fairly sure that this problem has been encountered before and hope someone can help me solve it.
I am running linux 2.4.18 on a MIPS 4Kc core with all tools configured as mipsel-linux, with glibc-2.2.4 and the corresponding version of pthreads.
When using GDB 5.3 I get strange errors and am basically not able to debug multi-threaded programs. For example any java program compiled with GCC/GCJ runs in multiple threads and does something like this:
# gdb PR218

This GDB was configured as "mipsel-linux"...
(gdb) b main
Breakpoint 1 at 0x400dec: file /tmp/ccr0H72i.i, line 10.
(gdb) c
The program is not being run.
(gdb) run
Starting program: /junk/PR218
[New Thread 1024 (LWP 103)]
Program received signal SIGTRAP, Trace/breakpoint trap. [Switching to Thread 1024 (LWP 103)] 0x00000000 in ?? () (gdb)
At this point no further debugging is possible.
If I attach to a particular thread after the program is started I can do some debugging, but that is inferior to having it work properly.
Q: Has anyone else seen this type of behavior from GDB?
Q: What is the solution?
Thanks in advance David Daney.
