Summary: WREC strange handling of very large minimum repetitions
Product: WebKit
Version: 528+ (Nightly build)
Platform: PC
URL: javascript:alert(/a{11111111111111111111}/.test("a"))
OS/Version: Linux
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: erikcorry at google.com
Probably some sort of overflow issue:
/a{11111111111111111111}/.test("a")
expected result false
actual result true
Pre-WREC this would give a parse error, which also seems fair enough. The
boundary was 65535/6.
