...and on further checking, the crash is not unique to PDL. See below.
Checking every piddle for valid data before passing them on to GSL would be
a major slow down, so perhaps a note in the docs would be useful. Unless
this is misbehaviour by Math::GSL, of course.

Using Math::GSL via sisyphusion.tk, strawberry perl 5.24.1:
C:\somedir>perl -MMath::GSL::SF -E"say Math::GSL::SF::gsl_sf_lngamma(1)"
0
C:\somedir>perl -MMath::GSL::SF -E"say Math::GSL::SF::gsl_sf_lngamma(0)"
gsl: gamma.c:1138: ERROR: domain error
Default GSL error handler invoked.
This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.
