Hi,
I’m getting a crash with latest trunk OSG (having not previously updated for
some time, eg six months or more).
(lldb) bt

The internalFormat and type values correspond to GL_ALPHA and GL_UNSIGNED_BYTE.
This case isn’t covered by the sizedInternalFormats array, so one would expect
the code to have the i counter reach 0, and the function return 0.
This is on clang, Xcode 6.1. Crash is reproducible in all kinds of builds
(release, debug, rel-with-deb-info) that I tried so far.
Given this code has been in OSG since June according to the blame/log, I guess
most people are not experiencing the issue, but I thought it best to ask here
before spending time adding debug logic to the code.
Kind regards,
James
