Fixes some hidden NULL pointer dereferencing.

'specMap' parameter can sometimes be NULL (when not in '-c' mode).
In code it was dereferenced before the check for '-c', but due to
compiler optimizations this was never revealed.

I found the bug while trying to measure the size of 'specMap'
before the check (caught segfault). Fixed by moving the check prior
to dereferencing.
