 Description  « Hide

I think since ~r13904 there is a repeatable failure when run the complete SPEC JVM is run with -m20 -M20 as shown here:

The change was an opt compiler change (to remove unreachable code) but it seems to have exposed a GC bug.

More recent results (r13907) without expression folding suggest that this is a bug somewhere outside of expression folding:

At least needs investigation before we can make release.

Running a full Spec JVM for 20 iterations since closing RVM-352 now completes.
