Segmentation fault when trying to use --auto-hint 1 #626

Open rsimmonsnim opened 8 years ago

rsimmonsnim commented 8 years ago

Great tool! I could use help with this issue though: I have a pdf file that is fine on Mac, but on Ubuntu 12.04.5 LTS (GNU/Linux 3.2.0-101-generic x86_64) I get a segmentation fault but only when using this option (--auto-hint 1), any ideas? Also runs ok on ubuntu if I don't try to process all 110 pages, seems like a real head scratcher. The results are better with --auto-hint 1, so I'd like to keep it if I can.

Here's my command line: pdf2htmlEX --tounicode 0 --optimize-text 1 --space-as-offset 0 --embed cfijo --process-type3=1 --correct-text-visibility 1 --process-nontext 1 --external-hint-tool=ttfautohint --auto-hint 1 --split-pages=1 --auto-hint 1 --hdpi 225 --vdpi 225 --dest-dir $outDir $inFile

Happens with many pdfs, here's the last screen of lines from debug output:

Although not 100% sure, it looks like a crash in FontForge. Can try this?
