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

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:
