Summary: [Windows] Parser asserts because sourceOffset !=
UINT_MAX
Product: WebKit
Version: 528+ (Nightly build)
Platform: PC
OS/Version: All
Status: NEW
Severity: Critical
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: bfulgham at webkit.org
Recent changes in the JSC parser are triggering an assertion in Windows because the sourceOffset is getting set to UINT_MAX.
Source location:
JSTokenLocation(const JSTokenLocation& location)
{
line = location.line;
lineStartOffset = location.lineStartOffset;
startOffset = location.startOffset;
endOffset = location.endOffset;
sourceOffset = location.sourceOffset;
>>> ASSERT(sourceOffset != UINT_MAX);
}
Local state:
-location {line=3 lineStartOffset=0 startOffset=341 ...} const JSC::JSTokenLocation &
line 3 int
lineStartOffset 0 unsigned int
startOffset 341 unsigned int
endOffset 342 unsigned int
sourceOffset 4294967295 unsigned int
location.sourceOffset 4294967295 unsigned int
sourceOffset 4294967295 unsigned int
-this 0x000cca20 {line=3 lineStartOffset=0 startOffset=341 ...} JSC::JSTokenLocation * const
line 3 int
lineStartOffset 0 unsigned int
startOffset 341 unsigned int
endOffset 342 unsigned int
sourceOffset 4294967295 unsigned int
