If malloc is interrupted, and the signal handler uses malloc, there's no
guarantee that malloc will function properly.  The same applies to stdio
and other things that operate on data in the user space.  Sometimes it
works, sometimes it doesn't.  (I'd like it to work all the time - back
15 years ago when I first was interested in sigwinch, it seemed to work
just fine using malloc in a signal handler, but that was BSD 4.3).
