Crash when attempting to convert a simple PDF file using mutool #243

Closed oakad closed 1 year ago

oakad commented 1 year ago

dvisvgm version 3.0.4 mutool version 1.22.2

The crash is as following (looks like an std::vector capacity issue):

Please provide a small PDF file to reproduce the issue. I guess it's the same as #242 which has already been fixed.

Attached. The failure indeed looks similar.
