    <thetext>Steps to reproduce:
1. Build WebKit with debug configuration and FTL JIT enabled.
2. Run &apos;./MiniBrowser https://octane-benchmark.googlecode.com/svn/latest/index.html&apos; from a terminal.
3. Click &apos;Start Octane 2.0&apos; in the web page.

Result:
Assertion failure shows in the terminal and WebKitWebProcess crashes when it runs the TypeScript test. If it doesn&apos;t crash, running the benchmark again is likely to crash it.

This bug was found while making FTL JIT work on FreeBSD, so I put links to backtraces instead of pasting them again.
