Description Omair Majid 2018-04-24 20:26:00 UTC

Description of problem:

I was trying to build .NET Core:

1. git clone https://github.com/dotnet/source-build
2. cd source-build
3. git checkout 8d7676baae31c0c6ccb76befec70738ee76c251f
4. git submodule init
5. git submodule update
6. ./build.sh

(Please note that .NET Core uses itself to build and due to a bug in .NET Core, the build does not support any terminal that uses the new terminfo format used in Fedora 28 and Rawhide. xterm+screen works. gnome-terminal+tmux does not work. Any terminal in Fedora 27 or earlier works.)

The build crashed. Here is the console output:

Disabling profile guided optimizations makes this build work. I can no longer reproduce the crash when I disable PGO.

Would you also be able to upload the profile data from:

/home/omajid/devel/dotnet/source-build/packages/optimization.linux-x64.pgo.coreclr/99.99.99-master-20180228-0037/data/clrjit.profdata

Comment 6 Omair Majid 2018-08-29 22:47:32 UTC

I can no longer reproduce the crashes with my original build steps. Not sure what got fixed where, though :)

Thanks for the help!
