I don't know, still I've to understand why we try to delete this
trampoline.
What I've understood from the trace is that `comp--native-compile' is
trying to delete the trampoline that was just compiled.
This is not expected in normal conditions so we have to understand why.
The only case where we might do that AFAIR is when
`inhibit-automatic-native-compilation' is used. This was the infamous
mechanism that was installed by Lars where, if I'm not wrong, we are
supposed to compile a trampoline, load it, and remove it to pretend we
didn't compiled anything :x
If (as I understand) in Windows we can't delete a mapped file we have a
problem more to solve.
Andrew do you happen to have `inhibit-automatic-native-compilation' set?
If not could we debug why we reach delete-file in this piece of code at
the end of `comp--native-compile'?
(when (and (not (stringp function-or-file))
comp-ctxt
(comp-ctxt-output comp-ctxt)
(file-exists-p (comp-ctxt-output comp-ctxt)))
(delete-file (comp-ctxt-output comp-ctxt)))
Thanks
Andrea
