Description Jerry James 2022-08-24 17:05:56 UTC

Description of problem:
As described in bug 2120809, texlive-base-20210325-poppler-22.08.0.patch does not handle a shared_ptr correctly.  In particular, GfxFont::makeFont can return a shared_ptr that has only a single reference.  The C pointer is extracted from the shared_ptr and saved, but the shared_ptr goes out of scope, resulting in deallocation of the font object.  The code later dereferences the saved C pointer, which by now can be pointing to anything.

Version-Release number of selected component (if applicable):
texlive-base-20210325-51.fc37

How reproducible:
Always.

Steps to Reproduce:
1. Try to build asymptote for Rawhide

Actual results:
pdflatex segfaults

Expected results:
pdflatex should not segfault

Comment 1 Tom "spot" Callaway 2022-08-24 22:27:11 UTC

Okay. I have a better version of that patch which seems more correct. In local testing, it resolves the pdftex segfault that an asymptote source build triggers.
