iraf.net Issue #128

noao.digiphot.photcal crashes on 64 bit

This issue is created on base of a forum post in 2013, taking the (shortened) data from there: x_photcal.e does not work correctly on 64 bit machines. Let’s take the following minimal observation list: File: sobs.dat

Running this gives a segmentation violation on 64-bit platforms:

This works fine for on 32 bit platforms (and the executable in the binary linux64 distribution 2.16.1 was silently replaced by the 32-bit version).

Travis CI run with this problem, with this test.

Fixed in #130
