I found myself a solaris box and was able to reproduce your bug.
To try to track down what was happening, I modified the code generated by
ffihugs and modified your test.c and Test.hs to check that the function
'times' gave the same result. Test.c and Test.hs both saw a return value of
-1 (hence the segfault) but the modified version of test.c didn't print
anything.
Hypothesis: there is a standard library function on solaris called 'times'
which is shadowing your definition of times.
To test this hypothesis, I renamed the C function being called to 'times_adr',
recompiled, reloaded and... it worked just fine.
Does anyone know of a flag you can pass to a linker to make it report an error
instead of silently doing the wrong thing?
