Thanks. That's the correct workaround.

It's not a workaround, it's a fix. ANSI C allows
malloc(0) to return 0.

I run u9fs on Tru64 UNIX but it gives `malloc(0) fails'.
I added the following fragment in emalloc() in u9fs.c.
I agree it could be an extremely nasty work-around.
/sys/src/cmd/unix/u9fs/u9fs.c:/^emalloc
void *p;
> if (n == 0)
> n = 1;
p = malloc(n);
if(p == 0)
(I used bundled CC, not GCC.)
