[disclaimer: I am not a programmer, but a chemist pinch hitting as a postmaster] Trying to trace the source of the problem, it seems to me that the absence of va_copy under HP-UX C is the culprit, but the workaround provided (macros.h) appears not to agree with the compiler. The hint provided in that file suggests that memcpy might be used instead, but I have no idea if that would work properly. > Some searching suggests issues with stdargs with HP-UX and some "sensitivity" > here. Apparently the native compiler has an "old C" mode and an ANSI C mode? > Can you ensure that you're using ANSI C mode? Apparently, this is the "-Ae" > option to the compiler. Perhaps we should add this to the commented-out form > for HP-UX CC in Makefile-HP-UX. > [http://docs.hp.com/en/B3901-90013/ch09s01.html] The ANSI C mode is the default, and indeed, adding the -Ae option does not change the outcome. > We do declare smtp_vprintf() before calling it, so the types should be fine; > exim.h pulls in stdarg.h before stdio.h, so the problems described at > [http://my.opera.com/EinSascha/blog/va-list-and-nonconforming-implementations] > shouldn't apply. > > So I'm at a loss.
