Segfault on specific domains #8

Open AsenOsen opened 3 years ago

AsenOsen commented 3 years ago

Did not dig into it, but some domains - like pftech.xyz provokes segmentation fault

petterreinholdtsen commented 2 months ago

I can reproduce the error. This is the last of the valgrind output when it crashes:

When running on a version where the changes in the open pull requests (as in the latest Debian upload) have been applied, the crash no longer happen:
