Please note the only failed sub-tests are those which load dynamically another shared library. Here is call stack from one of such crash:

F/libc (22596): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x1c in tid 22596 (test_dl_wrapper)

The same picture for other sub-tests. It's easy to see libbar.so call 'fputs' from libc.so instead of libcrystax.so, even though libbar.so was linked with -lcrystax before -lc. This looks like bug in crazy_linker which don't take care about order of symbols when resolving them on library load.
