 Miguel, why did you reassign the closed bug to me, it was RESOLVED
 FIXED in Bugzilla ?

+I had mistakenly closed the bug, but I'd reopened it, above.
+This bug looks like a memory corruption issue that's not easy to
+expose as a segfault (the 5/1 attachment, for example, crashes under
+--trace on amd64 but not under x86). To repro it I'd suggest one of
+the following routes:
+  - Running the first HashCrash.cs attachment under,
+  - _or_, running the BigTest.exe application that I've attached. I
+can provide the source, but it's not a small app; unfortunately it's
+the only one I've found that consistently causes the runtime to
+segfault on various architectures and versions of mono.
+This bug is important to me (I'm blocking on it), so I'd be happy to
+provide whatever information you need and/or to spend time debugging
+it, if someone can point me in the right direction.
