With remote stylesheets off and images off, opening http://www.dillo.org/test/long_alt_text.html and dragging the horizontal scrollbar left and right for a little while will make my machine suddenly start to page madly.
Whoooooohooooo!
Good catch: I got an instantaneous X server crash here.
Will look into it.
With XFT disabled, this page doesn't give me any memory difficulties.
*it surprises me*
I've found this:
* fl_width() returns OK when called by FltkPlatform::textWidth() * dillo-2.2.1 also crashes my X server.
With this little data I tend to think there's a bug in Dillo. Maybe a huge allocation request...
* There's no need to disable CSS nor images here to have a crash.
To discard an utf8 kill-sequence, I changed the testcase into a 1106 'a' character repetition (attached). After applying the attached debug-patch, it crashes consistently [1] with max_c=734 but not with max_c=733. I see the expected memory usage with max_c=733 .
Is this also true in your machine?
With 733, I scroll back and forth, and mem used in the Mem line in top goes up, up, up, while nothing out of the ordinary happens to dillo or X, and the paging begins, and it takes a minute or so to notice the ctrl-Q. A MSG() in drawSimpleWrappedText() says "width 5864 height 17", which adds to the evidence that it may not be a 16-bit overflow. 733 vs 734 makes no difference for me.
