Version 1.2.20 includes the following changes compared to 1.2.19:
- Fixed memory leak associated with the use of OpenSSL BIO (used when
OpenSSL provides the TLS functionality for the NIO and NIO2
connectors)
Various other fixes and improvements. See the changelog for details.
The proposed release artefacts can be found at [1],
and the build was done using tag [2].

I have a strange finding on Solaris running the TC 8.5 head test suite

SIGBUS on Solaris typically means an alignment error, x86 is more
tolerant in this respect.

Unfortunately gdb does give me the code line in apr where the crash
happens, so currently I don't know which address is broken.
I will do the same tests on Linux and will try to check against 1.2.19
and other OpenSSL versions. But that will take some time. Just wanted to
give a heads up, that something looks fishy on my boxes.

Rainer
