A stub in the dark: add the following switches to the temacs link
command line, then rebuild temacs, redump emacs, and see if the
problems go away:
-Wl,-disable-high-entropy-va -Wl,-disable-reloc-section
These disable the Windows ASLR, which could interfere with the
assumption that addresses that are recorded at dump time stay the same
when the dumped Emacs is restarted.
