crashlytics log

hi,

my app have a crash in crashlytics.com. the reason is the -[ASIHTTPRequest runPACScript:] , but too many JSC thread be hang up before the crash. finally as the memory too low , the system abort.

i search bug in webkit.org, example :
    https://bugs.webkit.org/show_bug.cgi?id=98084
    https://bugs.webkit.org/show_bug.cgi?id=90622

it refer to the free block in gc , especially follow code is not perfect. 

void BlockAllocator::blockFreeingThreadMain()
{
    while (!m_blockFreeingThreadShouldQuit) {
        // Generally wait for one second before scavenging free blocks. This
        // may return early, particularly when we're being asked to quit.
        waitForRelativeTime(1.0);
        if (m_blockFreeingThreadShouldQuit)
            break;


so can you verify this question is the bug in jsc? and how to fix it ?
