Comment 1 Timotheus Pokorra 2019-07-17 19:11:58 UTC

this issue might be similar: https://github.com/gperftools/gperftools/issues/1009
but I did not understand what the solution would be.

Comment 2 Dan Horák 2019-07-17 20:43:23 UTC

This is definitely not a problem with mono trunk, sounds like a change in the 5.18 branch, will take a look ...

Comment 3 Timotheus Pokorra 2019-07-20 21:08:23 UTC

Seems it builds in Rawhide without changes, according to Koschei.
I will close the bug on Monday, if the build succeeds.

Comment 4 Timotheus Pokorra 2019-07-22 05:07:05 UTC

It seems something outside of Mono was broken in Rawhide, it is working again.

Comment 5 Dan Horák 2019-07-22 10:27:27 UTC

It could have been caused by the kernel-headers package in Rawhide, it was broken for a short while after introducing 5.3-pre kernels.
