Go down  Message [Page 1 of 1]



This is a minor bug.

When you "Show Memory Table", there is a extra empty column between col 0xF and col 0.

As I was clumsy ennough to click a cell of this extra empty column, i found it makes Simulide crash.

Here is the backtrace :


Thread 1 "simulide" received signal SIGSEGV, Segmentation fault.

Ok... the narrow column used as "separator".
You are right, this column got forgotten, and this case is not handled properly.

A crash is always an important bug.
Someone can lose hours of work is they happen to get a crash.
Thank you very much for all the testing you are doing.
