Hi,
the time() syscall wrapper on i386 is inconsistent with the time()
implementations from time/time.c and sysdeps/unix/time.c as used on
other architectures.
On i386 time() returns in error case -errno, in the other implementations
for the other architectures -1 is returned and errno adjusted.
So I propose the following patch to get i386 back in sync with the
other architectures and make it conforming to POSIX:

That's no good solution. It still leaves the implementation
inconsistent with other archs. I've checked in a version which will
always crash on invalid pointers. This is how x86-64 works and likely
other archs with time support in the vdso.
