When I run the the openssl evptest suite in purify runtime memory usage
analysis tool
it reports lots of memory segment errors in the AES crypto functions.
If I build openssl with AES assembler code disabled the same test
runs without any errors from purify.
Anyone seen this before?
The test was performed on a RedHat Enterprise Linux 3.0 x86 32-bit system
Code compiled with gcc version 3.2.3
Test results attached.
