bug#12870: 24.3.50; Crash: assertion failed during garbage collect

[Andy Moreton]

Emacs built from trunk r110872.

Emacs crashed with an unhandled Win32 exception. This was caused by an 
assertion failure:

(I'm going through old bug reports that have unfortunately gotten no
responses yet.)

This crash wasn't handled at the time, and as this was reported more
than six years ago, I don't think there's much chance of making any
progress here, so I'm closing this bug report.  If you're still seeing
similar crashes in modern Emacs versions, please reopen.
