Description Jan Kratochvil 2007-03-25 14:08:29 UTC 
+++ This bug was initially created as a clone of Bug #189607 +++

After a fix of `Bug 232837: utrace: PTRACE_ATTACH of SIGSTOPped process hangs'
to update the ptrace(2) syscall behavior back to the kernel.org one GDB will
start to hang during attaching to a SIGSTOPped process.  A prophecy of mine.

sleep 1h &
pid=$!
kill -STOP $pid
gdb sleep $pid
[WILL HANG]
