Invalid attempt to read memory at address 0x0000000000000002

Hi I am having this Critical Error which doens’t shed a lot of light of what is going on.

Signal 11 caught.
Malloc Size=131076 LargeMemoryPoolOffset=131092
CommonLinuxCrashHandler: Signal=11
Malloc Size=65535 LargeMemoryPoolOffset=196655

Can anybody tell me what it means? What it refers to?

any callStack would be usefull if you can get one !

I just redit to give the stack :wink:

I looks like fail attempt of hot reload, when this is happening? did you write your own module class maybe? i can see your module being referenced but you missing symbols
