I just opened a solution using XS/master and it crashed within seconds.

Happened with Mono JIT compiler version 4.9.3.43 (2017-02/9ecfd9f Sat Mar 18 02:18:24 EDT 2017)

I've seen reports of this crash since 4.6, also with non-concurrent GC.

Also seen once on jenkins, but never been able to repro so far.
