Segfault with multi-threaded retainer profiling
I see the following program often segfaults when compiled and run like this:
% ghc -threaded -O2 -prof -fprof-auto segfault.hs -rtsopts
[1 of 1] Compiling Main ( segfault.hs, segfault.o )
Linking segfault ...
% ./segfault aaaaaaaaaaaaaaaaaaaaaaa +RTS -hr -N5 -V -A512K
# Segfaults, often within a minute.
It also seems to me that it segfaults more often/quickly when some other process is actively running on the same machine. I kept "ghc -e 'last [1..]' +RTS -A13G" running while making the test case. The machine I used has 4 cores, 8 HT threads and 16GB RAM.
