List-Unsubscribe: , List-Archive: Xref: main.gmane.org gmane.emacs.devel:6041 X-Report-Spam: http://spam.gmane.org/gmane.emacs.devel:6041 The widget_value structures are not Lisp data; they are explicitly allocated and freed. So I don't think GC is responsible for this. It appears to me that ASCII text got written throughout the last real widget_value structure encountered: int help = 875524, Boolean enabled = 'H', Boolean selected = 'i', enum button_type button_type = 1751607660, Boolean title = 't', struct _widget_value * contents = 0x6374616d, XtPointer call_data = 0x20646568, struct _widget_value * next = 0x746e7953 This appears to say "Hilight" and "matched Synt". (I suspect there are three other characters in between them that did not show up in this output.) The value of `help' is peculiar since it does not translate into ASCII text, and yet it does not seem like a valid value to be there (it would normally be a Lisp string object). One interesting question is what data is in core before the start of this object. Is any ASCII text present there?
