My guess is that you have a double-free somewhere, or there's a
buffer overrun. Or maybe some bad interaction with the GC, e.g.
if you tried to free a pointer from the GC heap.
That cant be a GC problem as rempas project is

I don't think so.
My idea was that if you dont have defined a copy constructor and
if an instance is assigned to another,

I don't think so. The assertion seems to be violated when
`malloc` is used. And when I assert the result in the `_ptr`
field. Really weird...

You are going to allocate memory using the system call of your
operation

Is there any possible that there is a compiler bug? I do use

The bad news is that I tested in an Linux Mint system (mine is an

I didn't as I suppose that it would had no problems as it works
for you. Either that, or it will be indeed a problem with my
Glibc.
I did run it now after your reply and it

I did stupid and unsafe things like malloc(0) and writing out

I guess it depends

Hello, not completely unrelated to your problem, I have also
