i still see this on ubuntu 8.10. test.c still gives sigtrap when breakpoint is
set on sleeping().

http://sourceware.org/gdb/wiki/FAQ
GDB does not see any threads besides the one in which crash occurred; or SIGTRAP
kills my program when I set a breakpoint.
* This frequently happen on Linux, especially on embedded targets. There are
two common causes:
o
you are using glibc, and you have stripped libpthread.so.0
o
mismatch between libpthread.so.0 and libthread_db.so.1
GDB itself does not know how to decode "thread control blocks" maintained
by glibc and considered to be glibc private implementation detail. It uses
libhread_db.so.1 (part of glibc) to help it do so. Therefore, libthread_db.so.1
and libpthread.so.0 must match in version and compilation flags.
In addition, libthread_db.so.1 requires certain non-global symbols to be
present in libpthread.so.0.
Solution: use strip --strip-debug libpthread.so.0 instead of strip
libpthread.so.0.
