[echesakov]

This started appearing pretty recently on macOS during Pri1 test build

packages/microsoft.netcore.compilers/3.0.0-beta3-final/tools/Microsoft.CSharp.Core.targets(52,5) corresponds to call to Csc task

I am not sure if this belongs to https://github.com/dotnet/coreclr/ repo or https://github.com/dotnet/roslyn/ but put it here for an initial investigation.

These tests were disabled in dotnet/coreclr#22774

@jashook Could you check if we've picked up a fixed Roslyn and reenable the test build if so?

[jashook]

Sure will do.

[janvorli]

We may want to use COMPlus_DefaultStackSize for our tests to override the default secondary stack size on OSX. It is only 512kB on OSX (as defined by the OS). The Linux default size is 2MB (see http://man7.org/linux/man-pages/man3/pthread_create.3.html#NOTES).

[janvorli]

Or, maybe better, make sure Roslyn works fine with that stack size Limit on OSX.
