Crash in getenv(3)

Is anyone else getting core dumps generated within getenv(3) ?

I'm trying to use an emulator for an old CPU but it crashes whenever I
switch focus to a different window.

(gdb) bt

The environment variable that SDL is looking for isn't set.

The emulator uses pthreads, sources are from last night but I have been
seeing this problem for several weeks.

I have got debug libraries built for this machine but haven't worked out
how to link against them yet.
