Hello, I got the same problem. @MagicalTux Did you already solve it and can you tell how, please?

[MagicalTux]

I haven't solved it yet but ___stack_chk_fail means the stack protector code is enabled somewhere but not linked in the end.

Adding -fno-stack-protector to the flags and rebuilding from a clean env should solve the issue.
