Enabling --enable-gc-assertions under gcc 4.6.2 in Mac OS X 10.7
causes all tests to fail.  The reason is the assertion in GC_add_roots_inner
that tests whether the address is on an word size 8 byte boundary.  But the
linker generated address "start" can fail that test, and it's added
in GC_dyld_image_add.  The value was 0x100122a44.
