Segfault in Ram Search

[micro500]

I am getting a segfault any time I try to run a ram search. I am running pcem as the game, but the same segfault happens with no game loaded.

libTAS version: Interim commit bb13477a built on 2022-09-27. This also happens with the libtas_1.4.3_amd64.deb release, but the backtrace cannot cleanly point to the failing line of code.

OS: Linux debian 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64 GNU/Linux
I am running this in Virtualbox on Windows 10.

GDB backtrace:

Looks like the error is stupid: you have been pressing Search while it should have been disabled and you need to press New

Looks like that was the problem. I did originally try clicking New but nothing happened, but I'm glad to see that issue is fixed as well. Thanks! I'll close this out.
