I was trying to use the virtual machine in 1.63 (but the issue may occur even in previous versions). If I don't have a .map file, the function list only contains the function addresses, it's not practically usable, but at least it works. However, if I provide a .map file, I get this error:
In case it's useful: the exe is written in C++ with heavy use of templates, so there are a lot of symbols in the map with 800+ characters in their name.Access violation at address 005466F0 in module 'Enigma.exe'. Read of address 02206E70.
