MobileTen is correct in that you’re more likely to get help from folks familiar with the third-party tooling you’re using. However, I have one thing I’d like to check before you head down that path. You wrote:

Exception Type:  EXC_BREAKPOINT (SIGTRAP)
…
Triggered by Thread:  8

but then posted a backtrace of thread 0, which isn’t helpful. Please post your full crash report. See Posting a Crash Report for advice on how to do that.

The lack of symbolication makes it hard to uncover anything but I believe that you’re hitting this trap

void StringBuilder::reifyString() const
{
    RELEASE_ASSERT(!hasOverflowed());
    …

Unfortunately I don’t know enough about WebKit to tell you what that means. It’s possible that the React Native community might have some ideas. Alternatively, you could ask the WebKit folks.
