:step hangs when -fbreak-on-exception is set
Stepping through code (that I can step through fine when -fbreak-on-exception is no set) hangs at the same place each time. The function I started stepping was in one module and the hang was in another (not sure if this is significant).
Ctrl+C returns to the prompt (no other output) and a further :step at that point causes a "not at breakpoint".
I wonder if the flag is causing something to be evaluated a second time (I understand that can cause :step to hang).
Erik first noticed the problem in Leksah, but I can reproduce it in GHCi without using Leksah to control it.
I'll try to get a minimal test case together.
