I also experienced coredumps with cygwin loading gif files, but rather
when Prima was compiled with libungif - libprigraph, on the contrary,
worked well. See, if it is really libprigraph and not libungif, Makefile.PL
reports what codecs are found. If it is, the only remedy is to compile
prigraph from source and see where's the problem. The source is
at http://www.prima.eu.org/download/libprigraph.zip, but be warned it is
a mess.

You might try simplier pieces of code to try, like,

   perl -MPrima -e 'Prima::Image->load(q(Prima/VB/VB.gif), index => 1)'

and see if it coredumps as well.

Not at all.

As far I have experienced, it uses something named like libprigraph.dll.a
for building executables that depend on libprigraph.dll, and libprigraph.a
(theoretically) is for the static linking, independent of the .dll,
although I didn't test for the latter case.

Thanks and happy new year!
