Comment(by simonmar):
The warnings about memory allocation are probably harmless, yes.
To avoid jumping into `handle_tick` when debugging, you can try `+RTS
-V0`, although removing `-threaded` is better (single-threaded is easier
to debug).
Since the problem appears to be related to `StablePtr`s, you might want to
check all the StablePtr-related code for bugs first, e.g. you might have
freed a `StablePtr` before using it. If you still can't find the bug, and
can't reduce the size of your program, but you can make it crash reliably,
then please do submit a bug report with instructions to reproduce it.
