JSFX Crashing on Out-of-Bounds Memory Access

Example JSFX:

Code:

@init

buffer = 0;
value = buffer[99999999999];

This works in REAPER v6.30/OSX64-clang rev 78eea5 (Jul 3 2021).

It crashes in v6.43: https://gist.github.com/leafac/abc9e...a7d573bcbce312

Thanks, fixing! This is an ARM-only issue, bge was used instead of bhs (signed vs unsigned)... this should affect 6.30 too.

Ohh, I get it. Yeah, I downloaded the Intel version of 6.30 because I know back then ARM was beta…

Thanks for fixing 👏
