I've now tried this change as well, but it doesn't help with our
problem. Whatever I try, gdb always immidiately receives SIGCHLD and
dies:

gdb /usr/bin/image-test 
GNU gdb 6.7.1

Using host libthread_db library "/lib/libthread_db.so.1".
(gdb) r
Starting program: /usr/bin/image-test 
warning: Can not parse XML target description; XML support was disabled
at compile time

[1]+  Stopped(SIGCHLD)        gdb /usr/bin/image-test


That's the same result that I also got with gdb 6.8, except that I
didn't get the warning about the XML target description with that
version.

Our platform is armv5tel with EABI
