Scott is right - the description of this attribute *has* changed.
Compare the current description to:
http://web.archive.org/web/20060824111504/http://gcc.gnu.org/onlinedocs/gcc
/Function-Attributes.html
Hence, either the attribute used to be incorrectly described and we were
just lucky not to
which already says ...
The malloc attribute is used to tell the compiler that a function may be
treated as if any non-NULL pointer it returns cannot alias any other pointer
valid when the function returns.

I've discussed this with Scott. He believes the description of the
malloc attribute has changed since libnih first started using it. The
current description does make its use in libnih and upstart invalid
seemingly.

according to http://gcc.gnu.org/onlinedocs/ this was documented from 4.1
on, didn't check earlier releases.

Title:
wrong usage of the `malloc'
A common convention in Upstart+NIH is for functions to accept a parent
pointer as in the following example:
Foo *make_foo (const void *parent) __attribute__ ((malloc));
Foo *
make_foo (const void *parent)
{
Foo *foo = nih_new (parent, Foo);
/* ... */
return foo;
}
But,
yes, that's my understanding.
