Thanks. Assuming this problem can be reproduced at will by the reporters, the best way forward is to use the technique described in etc/DEBUG for finding the infinite loop, in the section named "If the symptom of the bug is that Emacs fails to respond". But before someone does that, I suggest to rebuild Emacs without optimizations, as those can easily lead the investigation astray.
