I think this happens most often when I run this set of tests in parallel with another one or two tests in different console tabs.

@scheglov Can you expand what your d-rts script runs?

time dart /Users/scheglov/Source/Dart/sdk.git/sdk/pkg/analysis_server/test/test_all.dart

possibly on out of memory situation in some C code that does not have a check.

I haven't been able to reproduce this. Are you able to reproduce this with a coredump or under lldb?

@scheglov any luck on reprocing this with a coredump ?

I have not seen it for a while.

Closing issue, if you run into this again please open a new issue.
