Unable to load the http://www.youtube.com/tv on a target device. (error Log suggests ‘undefined’ invocation). JIT is enabled. Now when in JSC (Squirrel Fish Extreme), I disable JIT and rely only on the LLINT (C Loop) I am able to render the above page. On x86 version of the browser also I am able to load the above mentioned page. The details of the target device are as below Processor : ARMv6-compatible processor rev 7 (v6l) Features : swp half thumb fastmult vfp edsp java CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xb76 CPU revision : 7 Webkit Nightly Version: r-149577 It appears there is a timing or sequencing issue.
