Weak references related crash
I've been getting a Segmentation fault relating to Weak reference use as part of a FRP library (reflex). Attached is a more minimal example which crashes. With debugging on the original problem gave me these problems (on different runs):
Most frequently just Segmentation fault (with no stack trace)
Occasionally this:
bench: internal error: ASSERTION FAILED: file rts/sm/GCAux.c, line 44
(GHC version 7.10.2 for x86_64_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Aborted (core dumped)and more rarely this:
bench: internal error: WEAK object entered!
(GHC version 7.10.2 for x86_64_unknown_linux)
