I hit the following ASSERT on mibbit.com. It happens after I finish typing my username (but before I can tab away from that field). <http://trac.webkit.org/projects/webkit/browser/trunk/JavaScriptCore/pcre/pcre_exec.cpp#L1905> ASSERTION FAILED: subject (/Users/mlilek/Documents/WebKit/JavaScriptCore/pcre/pcre_exec.cpp:1905 int jsRegExpExecute(const JSRegExp*, const UChar*, int, int, int*, int)) Thread 0 Crashed: 0 com.apple.JavaScriptCore 0x004c5b9c jsRegExpExecute(JSRegExp const*, unsigned short const*, int, int, int*, int) + 130 (pcre_exec.cpp:1905) 1 com.apple.WebCore 0x01ef4706 WebCore::RegularExpression::match(WebCore::String const&, int, int*) const + 176 (RegularExpression.cpp:132) 2 com.apple.WebCore 0x01ef49f0 WebCore::RegularExpression::search(WebCore::String const&, int) const + 70 (RegularExpression.cpp:155) 3 com.apple.WebCore 0x01cfa985 WebCore::Frame::matchLabelsAgainstElement(NSArray*, WebCore::Element*) + 235 (FrameMac.mm:311) 4 com.apple.WebCore 0x020dd591 -[WebCoreFrameBridge matchLabels:againstElement:] + 63 (WebCoreFrameBridge.mm:626) 5 com.apple.WebKit 0x001bfc7c -[WebHTMLRepresentation matchLabels:againstElement:] + 58 (WebHTMLRepresentation.mm:320) 6 com.apple.Safari 0x00090fc7 0x1000 + 589767 7 com.apple.Safari 0x00091771 0x1000 + 591729 8 com.apple.Safari 0x00091491 0x1000 + 590993 9 com.apple.Safari 0x00091399 0x1000 + 590745 10 com.apple.Safari 0x0008bb23 0x1000 + 568099 11 com.apple.Foundation 0x91f29fce __NSFireDelayedPerform + 382 12 com.apple.CoreFoundation 0x933a7b5e CFRunLoopRunSpecific + 4494 13 com.apple.CoreFoundation 0x933a7d18 CFRunLoopRunInMode + 88 14 com.apple.HIToolbox 0x947f86a0 RunCurrentEventLoopInMode + 283 15 com.apple.HIToolbox 0x947f84b9 ReceiveNextEventCommon + 374 16 com.apple.HIToolbox 0x947f832d BlockUntilNextEventMatchingListInMode + 106 17 com.apple.AppKit 0x93a687d9 _DPSNextEvent + 657 18 com.apple.AppKit 0x93a6808e -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 128 19 com.apple.Safari 0x0000965e 0x1000 + 34398 20 com.apple.AppKit 0x93a610c5 -[NSApplication run] + 795 21 com.apple.AppKit 0x93a2e30a NSApplicationMain + 574 22 com.apple.Safari 0x00002a76 0x1000 + 6774
