Strange address sanitizer complaints by Apple clang #44

Open iboB opened 1 year ago

iboB commented 1 year ago

This happens when running the plugin demo with asan on mac:

It does not happen with clang15 on Linux and it seems that it shouldn't happen on mac as well.

More time needs to be invested here.

It seems that this is either a clang-14 issue or an apple-clang issue. I cannot reproduce this with clang 15 on Linux

iboB commented 1 year ago

Lowering the priority on this one. Will be done post v2.0.0

iboB commented 1 month ago

yep. It does not happen on apple clang 16
