Run "make V=1" to see the full command line of the command that fails,
then start "gdb ./emacs.exe" in the src directory, and copy/paste the
offending command line into the GDB command to run Emacs, right after
the "run" part.  Then wait until it segfaults.

That's too late: when a program running not under a debugger triggers
a fatal exception, Windows invokes the global exception handler, which
in this case is installed by the MinGW startup code, so you don't see
the application stack.  When a program is being debugged, the debugger
gets the first opportunity to handle the exception, so it can display
much more information.

Looks like some GC problem to me, as prin1 uses a temporary buffer to
produce its strings.
