Hi Justin,

I am maintaining Exim for the Blastwave project. I am actually just
preparing an Exim 4.62 package for Blastwave.

I am suspecting that the problems are related to you compiling Exim as
64 bit application. Has that worked before (with older versions) or is
this the first time you are trying?

I am wondering if anybody else has tried 64 bit Exim binaries on other
platforms/OSes and what their results were.

Which version of Sun Studio are you using to compile Exim?

Do you really *need* 64 bit address space? If it's just about taking
advantage of UltraSPARC extensions, you could always compile with
-xarch=v8plusa.

The segfault may very well indicate some 64 bit memory access issues. I
suggest you try 32 bit to see if it goes away.

If it's a 32 bit vs. 64 bit issue, the code obviously should still be
fixed, but running 32 bit for now might be a good work-around.
