I don't know if this is ueful; but I came across a similar issue
some months ago with a configure script for Fortran, where conftest.f
was vanishing. The culprit turned out to be an errant trap which was
being triggered elsewhere, which specifically deleted conftest.*, but
somehow didn't stop the configure script proceeding.

The ultimate cause turned out to be a buggy compiler on the platform in
question - unfortunately I can't remember precisely the details of how
that resulted in the odd behaviour; but I do remember it being very
difficult to find, until I discovered the trap in question.
