Description Andi McClure 2017-04-18 18:08:03 UTC
This issue has been fixed, this bugzilla is tracking the need for a regression test

+++ This bug was initially created as a clone of Bug #53890 +++

To reproduce:

$ git clone git@github.com:mono/msbuild.git
# xplat-master branch

$ ./cibuild.sh --scope Test --host Mono --target Mono

The above crashes while trying to run tests with xunit:

(partial trace here, full output log attached):

Also, complains:

EXEC : error : (i386) /Library/Frameworks/Mono.framework/Versions/4.9.3/lib/mono/4.5/mscorlib.dll.dylib empty dSYM file detected, dSYM was created with an executable with no debug info. [/Users/ankit/dev/msbuild/src/Framework.UnitTests/Microsoft.Build.Framework.UnitTests.csproj]

This is with mono from the 2017-02 branch, built on wrench few hours back (06060e29).

Full output log is attached.

This works fine with mono .

I was getting the same result with a recent 4.9.4.x, but I didn't try the latest from master.
Comment 1 Aleksey Kliger 2017-05-08 15:04:23 UTC
Changing importance since this is just about adding a regression test.
Comment 2 Marek Safar 2017-09-06 15:29:45 UTC
We run xunit as part of build now
