These are all excess failures exposed by adding -m64:

There are no useful error messages in objc.log, when I run the left behind excecutables by hand they simply bus error.

Running one of them under gdb I get:

Starting program: /teal/caip5/ghazi/gcc-testing/branch/build/gcc/testsuite/./formal_protocol-6.x0

Program received signal SIGBUS, Bus error.

bootstrap on solaris2.7 and run the testsuite with -m64
