I pulled several recent commits, and after doing so my release build of hugin is fine, but my debug build will no longer start.
I was unable to copy the text of the stack traceback. I hope the attached image of it is enough.
The problem seems to be that projParam.size() is nonzero (deep inside creating the huginApp object).
I'll try to figure it out. But it is not a section of code I ever looked at.
