[webkit-help] Older WebKit nightlies keep crashing

[Daniel Trebbien]

Hello,

I am attempting to use the Tools/Scripts/bisect-builds script to determine when a bug was introduced into WebKit.  The problem is that when the script runs a nightly that it downloaded, the WebKit nightly crashes.

So far, the r136849, r136812, and r136764 builds have all crashed with:

dyld: lazy symbol binding failed: Symbol not found: _WKPageSetInvalidMessageFunction
  Referenced from: /System/Library/StagedFrameworks/Safari/Safari.framework/Safari
  Expected in: /Volumes/WebKit/WebKit.app/Contents/Frameworks/10.7/WebKit2.framework/Versions/A/WebKit2

dyld: Symbol not found: _WKPageSetInvalidMessageFunction
  Referenced from: /System/Library/StagedFrameworks/Safari/Safari.framework/Safari
  Expected in: /Volumes/WebKit/WebKit.app/Contents/Frameworks/10.7/WebKit2.framework/Versions/A/WebKit2

The crash reporter info says the same thing:

Dyld Error Message:
  Symbol not found: _WKPageSetInvalidMessageFunction
  Referenced from: /System/Library/StagedFrameworks/Safari/Safari.framework/Safari
  Expected in: /Volumes/VOLUME/WebKit.app/Contents/Frameworks/10.7/WebKit2.framework/Versions/A/WebKit2


I tried out some other nightlies of WebKit that I had downloaded a while ago, and these are now crashing too.  The r130495, r134433, r135516, r135851, r136242, r136298, r137862, and r137986 nightlies all crash now, but they didn't crash at the time that I had downloaded them.  r138461 is the first nightly that I have which does not crash, but unfortunately, it has the bug that I am attempting to bisect.

I am running Mac OS 10.7.5 and I have Safari 6.0.4 installed.

Is anyone else seeing this problem?  Is there a way around it?
