Segfault reading binary sup file

[rudism]

I've got a bunch of sup files extracted from a bluray disk. All of them seem to produce a segfault when trying to process them. Here's a gdb backtrace:

I'm able to open the same sup files using subtitle-edit and see the subtitles OK. Here's the file from the backtrace above (zipped):

S01E04.eng.sup.zip

This was produced using a locally built copy, but I was encountering the segfault when using the docker method as well.
