xemacs & recent -current seems unstable

[Frank Kardel <kardel%kardel.name@localhost>]

Hi *,

has anyone also observed a serous instability with xemacs-21.4.17.
With recent -current (20080118) I get pretty fast xemacs
assertion failures like these:
Fatal error: assertion failed, file extents.c, line 833, foundp

Fatal error (6).

On older systems I seem to remember this xemacs being stable.
version 21.4.21 (fresh compiles) exhibits similar behavior.
also 21.4.13 compiled for i396-4.99.31 fails.

It sees strange that xemacs starts to act up.
