  * difficulty:  => Unknown


Comment:

 Clearly the segfault ought to produce an informative error message
 instead.

 However, the fact that the symbol is missing entirely is suspicious.  Is
 it possible that the .hi files are out of sync with the library object
 file?  If everything is in sync, we should investigate further to find out
 why the symbol is missing.
