The current CVS HEAD fails to bulid--there is an unexpected signal encountered when running runhugs. I attached the end of my build log below. This failure occurs on both platforms I tried: Ubuntu 6.06 and Windows XP.<br><br>
It seems the recent change to input.c is to blame:<br>* If any valid Haskell module (I tried A.hs containing [ main = putStrLn &quot;hello&quot; ] ) is substituted&nbsp; for hapax.hs on the command line, the unexpected signal still occurs. The problem is not specific to Cabal or 
hapax.hs.<br>* If a module with a syntax or typechecking error is substituted for hapax.hs, runhugs correctly reports the error and exits.<br>* If I check out the sources as of 2006-09-06 and then build Hugs, the build succeeds.
<br>* If I then &quot;cvs update -A,&quot; which gives me the new input.c, and then &quot;make&quot; the build succeeds<br>* If I &quot;make clean&quot; after running &quot;cvs update -A,&quot; and before rebuilding, the same unexpected signal error stops the build.
