dillo_port1.3: segfault someplace on reload of news.google.com

by rogerx.oss＠gmail.com

I've got a segfault using dillo_port1.3 by continuously hitting the Reload button with the following url: http://www.google.com/search?aq=f&hl=en&gl=us&tbm=nws&btnmeta_news_search=1… After about three or four taps, dillo disappears and I don't see anything within the debug output from the startx window. (Using DWM and manually starting startx within a terminal here.) I don't think I've compiled with -g, -ggdb, etc... but here's what I've got so far. I'll try to bit-bang this a little bit more tomorrow when I get time if nobody else gets this. My guess so far, when running within GDB, reload button works continuously without crashing until I start clicking before the page finishes reloading, then segfault. So, scanning gdb bt, this looks like it might get into fltk-1.3 buttons. This is all I've got so far: Connecting to 74.125.127.103 a_Nav_expect_done: reload!
