InvalidDVIFileException in upTeX DVI only on Solaris

[t-tk]

I wrote a test of dvisvgm for upTeX DVI and I have gotten core dump only on Solaris environments.
If you have any idea to fix it, I'm glad to have your advise.

Unfortunately, I have no idea. The logs contain too little information to determine the cause of the exception. I don't have access to a Solaris system either, so I can't debug this issue.

I tried to investigate this a little further but without much success. Since the exception leads to a core dump which should not happen (because all exceptions get caught in the code), I suppose this is a bug in GCC 5.5. Thus, I suggest to test it again with a newer version if possible.

The warning messages are related to the map file that probably doesn't contain information on the font files assigned to the mentioned font names.
