So my C code segfaults. Nothing new or interesting about that, let's just sprinkle the code with printfs and fire up gdb. malloc(24)GNU QUALITY

Because your precious new doesn't call malloc somewhere deep inside all that shit.

If you don't need a lot of memory and/or complicated management, you can implement your own malloc that allocs from an extern array.

Perhaps you are allocating more memory than the machine can spare, or perhaps you are leaking memory.

That's because you have doubly free'd a pointer or stepped out of bounds of a previously allocated array before calling malloc.
This typically happens when you have forgotten a
sizeof in a previous malloc.
Note that these lead to undefined behavior which includes a segmentation fault in your malloc call.

Yes, you are right. I'm retarded. I'd like to apologise to everyone involved in GNU project.

This happens on Windows' CRT too if you corrupt the block headers in the wrong way.

if you want exact 24 bytes why don't use a static array?

I, of course, was calling it with sizeof some struct (of size 24). I put 24 there just to be clear that I don't try to allocate something stupid.
