    Could you provide more details (sdcc --version output, maybe even check in which function it hangs using gdb or such)? I don't see the problem when I do a quick test using sdcc from trunk on my Debian GNU/Linux testing on amd64 system.

    this is from latest SVN [r16545]
    the test is currently disabled in MakeList
    you should be able to repro by enabling it.
