These are the only differences then.  Well I'm using Red Hat
Linux on ia32.

sorry, I have that too.

same here.


Any advice on how I can debug the problem further.  A gdb
backtrace seems to say that it gets stuck in a loop in
attr_set in libncurses.so.5.  Indeed my own debugging of
CursesTest.hsc told me that it segfaults during the attrSet
calls.

How to proceed from here.  Linking with a debug version of
libncurses?
