I have no idea how it exits, all that is passed back is from the
parent process, which is exiting 'zero' after a clean fork.

Maybe. What I can tell so far is the following:

- when compiled with "-Ae -O" exim -bd dies silently without
(=before) touching any log or pid file. (In a former statement
saying the opposite I was confused by entries from a debugged
exim a colleague had started almost the same time.)

- exim -bd runs as soon as the compile optimization level is
smaller than 2, that is, setting +O0 or +O1. An attempt to
selectively reduce inlining also failed, so the cause lies
somewhere in global optimizations.

A working solution for the C.06.00 compiler is to compile exim
with CFLAGS set to "-Ae -AOe". The result looks fine so far.

Kind regards,
