adm$ ./run-safari --debug
Starting Safari with DYLD_FRAMEWORK_PATH set to point to built WebKit in /Users/adm/Documents/Xcode/Webkit/WebKitBuild/Debug.
ASSERTION FAILED: to.m_offset != -1

Sorry, accidentally hit Enter

Compiled a Debug Build using the script on my MBP running Snow Leopard.


adm$ ./run-safari --debug
Starting Safari with DYLD_FRAMEWORK_PATH set to point to built WebKit in /Users/adm/Documents/Xcode/Webkit/WebKitBuild/Debug.

This opened to an empty window as it should. Then I navigated to www.google.com, as a relatively innocuous website, and this assertion occurred:

ASSERTION FAILED: to.m_offset != -1
(/Users/adm/Documents/Xcode/Webkit/JavaScriptCore/assembler/X86Assembler.h:1535 void JSC::X86Assembler::linkJump(JSC::X86Assembler::JmpSrc, JSC::X86Assembler::JmpDst))

Then Safari hung for awhile and finally crashed.

And this time I forgot to specify the build revision of r67834. Apologies.
Comment 3 Alexey Proskuryakov 2010-09-20 11:46:16 PDT 
Should be fixed in the next nightly, thanks for the report!
