Have you noticed this paragraph in mod_ssl's INSTALL file?
NOTE: RSAref has some portability problems. Especially it assumes that
an `unsigned long int' represents a four byte word. One result of
this bad assumption is that it fails under run-time (not
compile-time) on platforms/CPUs, like Alphas, where larger integer
sizes are used by the compiler. For instance when mod_ssl's `make
certificate' command hangs, you get memory faults or Apache hangs
when connecting to it through HTTPS, this all indicates that you
ran into this portability problem. The solution is to replace the
`typedef unsigned long int UINT4' in rsaref-2.0/source/global.h,
line 26. The best is to use `typedef u_int32_t UINT4' when
`u_int32_t' is defined by your vendor include files. If not try to
use a standard type which is four bytes in length on your
platform, e.g. on Alphas `typedef unsigned int UINT4' works.
Perhaps your SGI box has a similar problem?
