By comparing the stack trace of this issue it looks similar to   bug 807519  , hence assigning to the same owner for more updates on this issue.

drott@ Could you please take a look in to this issue?

Summary: Abrt in [vdso] after GetVerticalTranslationsForGlyphs (was: Abrt in [vdso])
I cannot reproduce this, I've built my Chrome locally with the same GN settings as the crash report, but I can't get it to crash in the same way. I assume the font configuration of the ClusterFuzz bots may differ from what I have locally and it's thus not reproducing in the same way.

Removing Reproducible, marking as WontFix.

I'll file a bug about ClusterFuzz' font configuration.

This is probably identical to  issue 807519  but I won't dupe it for now as it is a different fuzzer bot configuration.
