Update locstr.h to fix issue #18. #19

Closed sam-ellis closed 7 years ago

sam-ellis commented 7 years ago

Fix for issue #18. As per the comments in locstr.h the str field is permitted to be NULL. This fix protects against NULL pointer dereference in the << operators. This allows elkhound/elkhound elkhound/examples/crash1.gr to pass (not segfault) on Mac OS X.
