I thought the main point of moving to SIGTRAP was to preserve register state?

That said, there are probably places where we care more about the message than the registers.

One of the upside (side-effect) of adding this call is that it appears to stop the compiler from aggregating all the RELEASE_ASSERTS into a single code location, and this will help with post-mortem crash debugging.
