Program hangs when adding item to seq

[jamesleboulanger]

Hi everyone,

I am starting to learn Nim and I'm encountering a weird issue where the 
compiled program will hand (no response, even pressing Ctrl+C won't stop the 
program) when adding an item to a Seq.

Here is the code so far : 
[https://github.com/ronangaillard/psx-emu](https://github.com/ronangaillard/psx-emu)

The program hangs at line 10 of file src/core/interconnect.nim. ( I know this 
because I put echo commands before and after this.memoryZones.add(mz) and the 
echo after would not print.

Here is my current configuration :
    
    
    nim -v
