I'm stumped.
It is exiting gtk_main, but then both a normal exit and abort() just hang, and hang the debugger too.
ps -a shows the process as <defunct> which leads me to https://en.wikipedia.org/wiki/Zombie_process only there's no child/parent relation here at all.
The only other thing I could try is that opAbort is implemented in pStack as
[ELF64]
mov rdi,rax -- error_code (p1)
mov rax,60 -- sys_exit(rdi=int error_code)
syscall
whereas exit_thread ended up as
[ELF64]
-- xor rbx,rbx
-- mov rax,60 -- sys_exit
-- syscall
xor rdi,rdi
call "libpthread.so.0","pthread_exit"
So I'm thinking along those lines for trying glibc/exit(), but I can't remember how/where I ever figured the last line out...
(mind you, even if/when I figure that out, I'm betting it won't change a thing, though https://stackoverflow.com/questions/46903180/syscall-implementation-of-exit suggests it might.)
