I guess my question as a fairly naive user is who will bedoing that GC debugging. I am happy to check things in gdb following instructions from one of you experts...

When GC encounters a fatal inconsistency in the Emacs data structures,
it is generally unsafe to say anything, since that could easily cause
a nested fatal signal.

I'm not sure I'm such an expert on this, but the file etc/DEBUG has a
special section on debugging crashes inside GC.  I don't think there's
a general recipe, one just needs to follow the advice in etc/DEBUG and
find out the corrupted data structure.  Once the bad data structure is
found, the next step is to trace its life cycle and find what piece of
code corrupted it.
