See e.g. https://ci.dot.net/job/dotnet_coreclr/job/master/job/jitstress/job/x64_checked_windows_nt_gcstress0x3/19/

The most frequent cause appears to be this assert:

Assert failure(PID 7408 [0x00001cf0], Thread: 3568 [0x0df0]): generation_allocation_pointer (youngest_generation) == nullptr\r\n\r\nCORECLR! WKS::gc_heap::fix_youngest_allocation_area + 0x26 (0x00007ff8`cbe5bf4a)

@swgillespie @Maoni0 can one of you take a look?

This assert was introduced in dotnet/coreclr#10065, I'll take a look.

I think I know what's going on here and I hope to have a fix out soon.
