I'm on a 32bit Debian intel system.  libgc is 7.2alpha4

git describe is
v2.0.3-82-ga2c6601

The single failure running make check is

Running gc.test
FAIL: gc.test: gc: Lexical vars are collectable

In the end that failed.  I pushed a different patch that tried to NULL
out recursively called C stack frames.  Perhaps it worked?  As tests are
passing, I will close this one for now.  It's possible that simply
recursing through the VM wouldn't work well, as there might be stack
slots in vm_engine that don't get set in all code paths.  If we see
errors in the future, let's just mark those as flaky and move on.  Let's
also try to reduce the number of UNRESOLVED results in general, so that
these hacks will be more visible.

Regards,

Andy
