Hi!
When building openssl-0.9.3 on HP-UX 9.07 with the HP-UX native unbundled cc,
exptest dies with a floating point exception before even displaying the first
dot. This is independent from compiler optimization settings and reproducable
on different hardware. The stack tracebacks differ due to random data, but here
are some of them:

Used settings for this test were:
OpenSSL 0.9.3 23 May 1999
built on: Wed May 26 11:45:15 CES 1999
platform: hpux-cc
options: bn(64,32) md2(int) rc4(ptr,int) des(ptr,risc1,16,long) idea(int)
blowfish(idx)
compiler: cc -DB_ENDIAN -DBN_DIV2W -Ae +ESlit -g -z
The 0.9.3 exptest works fine when linked with the 0.9.2b libcrypto.
Bye, Andy
