Crash When Including Log Code

[victorstewart]

Whenever I include any usage of RedisModule_Log, Redis crashes when I try to load the module. Any ideas here?

Doing this inside docker fyi.

Example of usage...
RedisModule_Log(ctx, "warning", "RedisModule_OnLoad, argc = %d", argc);

Example of crash...
