Lemur Editor Crash on macOS when Deleting Expressions set with Strings

Michael Hurwitz Oct 11, 2016 03:17AM CEST

Steps to reproduce:

- Create a Container with 128 expressions and initialize each with fill(1, 'hello', 256);
- Copy the Container 2 times so you have 3 Containers.
- Delete TWO of the Containers-- the problem only occurs when you delete TWO.
- Lemur Crash

Something to do with dereferencing Strings? The problem only occurs when the expressions have been initialized with Strings-- Floats/Ints OK.

Problem isolated to macOS (Windows 10). Tested on El Capitan.

Thanks :-)
