[Box Backup-dev] Problem/unportability with malloc(0) on AIX

[Stefan Norlin]

Hi,

in my porting efforts on AIX I have comes across that
sometime malloc is called with a size argument of 0.

On Linux a pointer is returned anyway while on AIX
NULL is returned (with errno set to EINVAL) and an
exception is thrown.

I am unsure whether the malloc(0) call is correct first
place but the behavor is anyway different on different
OS:s.

Any comments on this and any ideas how to handle it?

There is a long discussion regarding this here:

With some hotfix using "mallopt(1, 0)".

Regards,
Stefan
