Intermittent segfault when using ghc-7.6.3 -e on OSX 10.6.8

This error was observed using the 64-bit version of ghc-7.6.3 packaged with the Haskell Platform 2013.2.0.0 for OSX.

Running commands with ghc -e sometimes produces a segfault.

% ghc -e 'return ()' ; echo $?
0
% ghc -e 'return ()' ; echo $?
zsh: segmentation fault  ghc -e 'return ()'
139

I don't know exactly what's causing it, but I'm suspicious of the binary distributed with the package. When I pull it up in gdb, there are warnings pertaining to missing object files expected to be in a /Users/ian directory. There's never been an ian user on my machine, so I suspect that's an artifact from whomever built the binary. This may also be the root of the intermittent segfault
