just use an assert, you'll never see OOM

OOM is like that beast from X-Files s5e19

I have OOM errors regularly. 1Gio RAM and no swap ; shit's no fun.

The name is misleading, it should be icalloc and not imalloc.

When reality runs out of memory locally, you get black hole expansion.

Either download more memory, or allocate everything statically. initab is never that complex that you would run out of static structures. Better still, just use the loaded file as storage. And just train those processes to behave better instead of hogging all your memory.

Should change to POSIX signal handlers.
