Subject: Who's maintaining the Win32 display code?
Date: Tue, 16 Sep 2003 20:30:53 -0400 [thread overview]
Message-ID: <u4qzcmf2a.fsf@boost-consulting.com> (raw)
I've been reporting these crashes for several months; is anyone going
to try to track this down or at least give me some pointers? If not,
maybe as I suggested earlier Win32 should be dropped as a target
platform. I've done my best to debug the code, but without some
guidance as to what's supposed to be happening, I'm lost. I can say
that it appears to be trying to draw my cursor. In w32_text_out(),
s->gc->font appears to be garbage and s->font appears to be valid.
There appear to be many ways to get to a W32FontStruct from a
glyph_string*; I have no idea whether any or all of them are supposed
to match up, but I am guessing that there's a lot of redundancy here
and the invariant is too complicated to be easily maintained. Anyway,
that's about all I can contribute: stack traces and speculation.
I'm very discouraged :(
