Here is a boiled-down snippet of nonsense code (it started as part of
the snow zlib package).

This is bug in the previous "fix" for checkInlineable.
I don't yet have a satisfactory fix - still working on it.

After many false starts, I have a fix that seems to work.
Sorry for the delay - this was the sort of painful problem that
encourages procrastination ...

Here's a similar one that seems to sidestep this fix.

This one turned out to be different - or at least the fix
was in a different area of the compiler.
The problem was accessing a function's static link. This was
done in a way to access an intermediate static link after the
latter had gone out of scope. The fix was to tweak how we
access the static link for inlined functions.
I checked in your testcase as testsuite/inline2.scm.

Thanks! I'm able to run snow's zlib library, now.
