Aha.
I've also recieved unaligned access errors, allthoug without running into a
crash, in other situations.
I remember recieving it every time I access one of the following :
mysqladmin status
mysqladmin processlist
mysqladmin extended-status
mysqladmin variables
I haven't checked if it is all of them or just one of them, but I get one
"unaligned access" error every time I access a PHP page containing these as
systemcalls.

I'll try debugging next week.
I'll debug the Compaq CC/C++ compiled version, since this is the one I hope
to get working (it generally produces faster & smaller binaries on Tru64
than GCC).
One thing btw. for the MySQL INSTALL-SOURCE Tru64 documentation : Might be a
good idea to add that in order to compile recent MySQL versions (> 3.22.x)
one has to upgrade the make utility. The one present by default on all Tru64
versions until 5.1 is not able to make MySQL. I haven't checked if the one
present on 5.1 or 5.1A is better.
