More experiments show that you can set your data segment size soft

limit higher and thereby get through compilation of sha_dgst.c.

On some Alpha installations running True64 Unix and Compaq C, the compilation
of crypto/sha/sha_dgst.c fails with the message 'Fatal: Insufficient virtual
memory to continue compilation.' As far as the tests have shown, this is a
compiler bug. What happens is that it eats up resident memory (not the swap)
until the current limit is reached and then dies with the error message given
above. The bug in question is clearly in the optimization code, because if
one eliminates optimization completely (-O0), the compilation goes through
(and the compiler consumes about 2MB of resident memory instead of 128MB or
whatever one's limit is currently). The very quick solution would be to
compile everything with -O0 as optimization level, but that's not a very
nice thing to do for those who expect to get the best result from OpenSSL.
A bit more complicated solution is the following:
memory to continue compilation.' As far as the tests have shown, this may be
a compiler bug. What happens is that it eats up a lot of resident memory
to build something, probably a table. The problem is clearly in the
optimization code, because if one eliminates optimization completely (-O0),
the compilation goes through (and the compiler consumes about 2MB of resident
memory instead of 240MB or whatever one's limit is currently).
There are three options to solve this problem:
1. set your current data segment size soft limit higher. Experience shows
that about 241000 kbytes seems to be enough on an AlphaServer DS10. You do
this with the command 'ulimit -Sd nnnnnn', where 'nnnnnn' is the number of
kbytes to set the limit to.
2. If you have a hard limit that is lower than what you need and you can't
get it changed, you can compile all of OpenSSL with -O0 as optimization
level. This is however not a very nice thing to do for those who expect to
get the best result from OpenSSL. A bit more complicated solution is the
following:
