I ran the test suite on OpenBSD 5.1 i386 and amd64, with objc from gcc 4.2.1.
GNUstep base last release.

when compiling on i386, I get this warning:

other warnings ar only:

one failed files, and one dashed hope.

It seems, something is overwriting the stack canary.

icu4c-4.8.1.1       International Components for Unicode


I'll try on a newer OpenBSD 5.2 beta i386 (with libobjc2) and macppc later
