On Linux, man abort says:
If the SIGABRT signal is ignored, or caught by a handler that returns,
the abort() function will still terminate the process. It does this by
restoring the default disposition for SIGABRT and then raising the sig‐
nal for a second time.
However I have a suspicious that I've seen abort() return on some
other OS in the distant past, maybe SunOS 4.
I wouldn't rely on abort() always terminating the process on all OSes.
