Hi David, I can reproduce this (or at least a very similar issue) seemingly every time on 32-bit PowerPC. All three of my uploads to Debian failed to build on it (across different machines) and I can reproduce it on another box. It happens with both jessie and unstable; below is the state of all the threads when I built it on unstable with two calls to "make compiler" followed by a "make check" (though ./poly --script Tests/Succeed/Test166.ML also hangs, so the test harness and running other tests first is irrelevant). Do you have access to a PowerPC machine you can put Debian on? If not I can probably arrange getting you remote access to one.
