I do not see any crash when using WebKit r15930. Test page is below. Please reopen the bug if you can provide more information -- a page that demonstrates the crash would be ideal. <html> <head> </head> <body> <div style='border-top: 3px #FFFFFF dashed'> &nbsp; </div> </body> </html>

Sorry after more testing the bug is associated with the -webkit-border features. The crash can be reproduced in the lasted nightly as of 8/21/06 with this code: <html> <head> <style> div#header { height: 100px; width: 75px; -webkit-border-bottom-right-radius: 10px; -webkit-border-bottom-left-radius: 10px; background: #FFF; } #navigation { height: 50px; width: 25px; -webkit-border-bottom-right-radius: 10px; -webkit-border-bottom-left-radius: 10px; border-top: 3px #FFFFFF dashed; background: #CCC; } </style> </head> <body> <div id="header"> <div id="navigation"> &nbsp; </div> </div> </body> </html>

Actually, I got a freeze, not a crash: 300 WebCore::RenderBox::paintBoxDecorations(WebCore::RenderObject::PaintInfo&, int, int) 300 WebCore::RenderObject::paintBorder(WebCore::GraphicsContext*, int, int, int, int, WebCore::RenderStyle const*, bool, bool) 300 WebCore::RenderObject::drawBorderArc(WebCore::GraphicsContext*, int, int, float, WebCore::IntSize, int, int, WebCore::RenderObject::BorderSide, WebCore::Color, WebCore::EBorderStyle, bool) 300 WebCore::GraphicsContext::drawArc(WebCore::IntRect const&, float, int, int) 300 CGContextDrawPath 300 ripc_DrawPath 300 ripr_Path 300 CGPathApply 300 ripr_path_stroke 300 path_dash_iterate 300 cube_length 300 cube_length

Bug 9202 talks about the same hang. Basically, it's a consequence of division by zero when the arc-painting code is invoked with a zero radius (for one of the corners that you don't specify a radius for) and dashed style. This should probably be closed as a duplicate of bug 9202.
