I can start a new one, but I cannot (easily) build a modified Emacs as
long as the crashed session runs.  And even if I do build a new
version, as soon as I "git pull", the sources will not match the
binary in the debugging session, and debugging becomes ... interesting.

Core dumps aren't supported on Windows.  As for testing the dynlib
hypothesis: how can this session help?  If this is the problem, it
already happened, and the Emacs process is already all but dead: it
hit a fatal assertion violation.  I cannot run the debuggee anymore,
all I can do is examine existing variables.  If there are some
variables you want me to examine, please tell, and I will report their
values.
