Steps to reproduce: 1. Open Safari/WebKit. 2. Make sure the "popunder" cookie for network-drivers.com is NOT set via Safari preferences. 3. Make sure "Block Pop-Up Windows" is NOT set. 4. Command-click on URL: http://www.network-drivers.com/drivers/53/53064.htm Expected results: The page should open without an assertion failure. Actual results: The page causes an assertion failure and Safari/WebKit crashes on a debug build. Regression: Not tested for regression with Safari 2.0.4 yet.

shipping Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037). Tested with a local debug build of WebKit r19943 with the above software. 20689 2 ap 2007-03-02 11:16:42 -0800 I cannot reproduce this on a PowerPC Mac. 20694 3 ddkilzer 2007-03-02 11:45:17 -0800 (In reply to comment #2) > I cannot reproduce this on a PowerPC Mac. Weird! I can't reproduce this with my PB G4, either. Local debug build of WebKit r19943 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8L127). 20703 4 ddkilzer 2007-03-02 13:46:27 -0800 (In reply to comment #2) > I cannot reproduce this on a PowerPC Mac. The issue is most likely caused by differences in how NaN floating point values are handled on PowerPC versus Intel architectures. Obviously, this code from StringTruncator.cpp (line 109) returns true with a NaN on PowerPC, but false with a NaN on Intel: ASSERT(maxWidth >= 0); I added an additional ASSERT() macro to the Intel debug build: + ASSERT(!isnan(maxWidth)); ASSERT(maxWidth >= 0); And rerunning the steps to reproduce demonstrated that maxWidth was a NaN value: ASSERTION FAILED: !isnan(maxWidth) (/Users/dkilzer/Projects/WebKit/WebCore/platform/StringTruncator.cpp:109 WebCore::String WebCore::truncateString(const WebCore::String&, float, const WebCore::Font&, unsigned int (*)(const WebCore::String&, unsigned int, unsigned int, UChar*))) Segmentation fault Not sure if we need to determine where the NaN is generated, or simply handle the NaN case differently in the truncateString(const String& string, float maxWidth, const Font& font, TruncationFunction truncateToBuffer) method. 20451 5 webkit 2007-03-02 15:28:25 -0800 This bug is hard to reproduce. The steps that I take to reliably test the bug are: 1. Open Webkit 2. Make sure the "popunder" cookie for network-drivers.com is NOT set via Safari preferences. 3. Set "Accept Cookies" to Never. 3. Make sure "Block Pop-Up Windows" is NOT set. 4. Command-click on URL: http://www.network-drivers.com/drivers/53/53064.htm 5. Repeat step 4 until you see detailed popup that contains bar graphs. So far I have isolated the bug to between WebKit-SVN-r17653.dmg (works) and WebKit-SVN-r17656.dmg (crashes). I have an iMac G5 and 10.4.8. 20459 6 13457 webkit 2007-03-02 16:30:40 -0800 Created attachment 13457 Reduction Command-click to open this attachment to crash Webkit. I believe that this bug is a GC-related error. The original page can be fixed by removing the "left=85,top=20," from the popup parameters. Accessing the zero index of an array and either a left= or top= parameter are necessary for this crash. 20565 7 mrowe 2007-03-05 00:23:46 -0800 The root of this problem is that kjs_window.cpp:1616 calls WebCore::screenRect with null as the argument. This results in toUserSpace invoking Objective-C methods on nil objects, which will either return zero or an undefined value depending on the return type of the method in question. This looks to cause userRect to be scaled by NaN, eventually leading to the assertion failure mentioned in this bug report. One strange thing I noticed while debugging this is that the x/y/width/height members of the WindowFeatures structure are not initialized, and in many cases are used before initialization. This could lead in some cases for windows created via window.open to have arbitrary sizes and locations while still being constrained within the screens bounds. 20567 8 13477 mrowe 2007-03-05 00:51:36 -0800 Created attachment 13477 Patch 20570 9 13477 mrowe 2007-03-05 01:36:32 -0800 Comment on attachment 13477 Patch I didn't include a layout test in this patch as I didn't see any way to test popups via DRT. 20573 10 mrowe 2007-03-05 01:56:58 -0800 Landed in r19961. 20434 11 ddkilzer 2007-03-05 04:01:52 -0800 (In reply to comment #9) > I didn't include a layout test in this patch as I didn't see any way to test > popups via DRT. Do we need a separate bug to implement this feature in DRT? Should DRT be dumping the list of pop-up menu items in each pop-up?
