It was on a machine to which I no longer have access; but it was an old-ish Digital Unix machine ... Ah-ha - I've just realised that I emailed the mailing list at the time http://lists.gnu.org/archive/html/autoconf/2004-07/msg00077.html And it looks like I was misremembering slightly. There was also a buggy compiler on that system, but it had nothing to do with the problem, which was actually conftest.c disappearing, and as you probably saw when you searched earlier - it was all due to a buggy shell (very old bash version) So - probably irrelevant; sorry. Still - if you do have a magically disappearing file, I would try and put some echo output into all the traps to see if it is a trap being triggered.
