Error: `c++ top level` when Translating C Files & Memory Leak Warning #51

Open ThisNekoGuy opened 2 years ago

ThisNekoGuy commented 2 years ago

Was trying to run v translate (which compiled c2v automatically) on raudio.c from: https://github.com/raysan5/raylib/blob/master/src/raudio.c and it failed like this:

neko-san@ARCH /m/e/D/raylib (master)> v translate *

(I just moved the aforementioned glfw folder somewhere else temporarily, so this shouldn't be related? I mention that because leaving the "glfw" folder in the project throws other errors)

@ medvednikov said this about it on Discord: "it sounds like a bug, it shouldn't allocate this much memory"

Got a similar error, but without the memory leak part. 

C:\Users\bazoo\Downloads>v translate enet.h
C to V translator 0.3.1
   translating enet.h          ... C++ top level
C2V command: "C:\Users\bazoo\.vmodules\c2v\c2v.exe" "enet.h"
C2V failed to translate the C files. Please report it via GitHub.

File I was trying to translate: https://github.com/zpl-c/enet/blob/master/include/enet.h

Similar error here too:
