I've had a look and I think there is a kernel bug here - specifically affecting 32-bit programs run on 64-bit kernels (like all the Debian buildds and the porterbox are). An extra PTRACE_SYSCALL stop is happening which confuses everything. I'll look some more tomorrow. The test passes OK if it's run on a 32-bit kernel though so the kernel does somewhat support it.
