Hi Michael Mueller Thank you for answering. So if I understand you correctly you also use the "build.info" file to specify the static libraries as dependencies for the 'openssl' binary. Do you encounter any segmentation faults when running the tests provided by OpenSSL in the openssl/test/recipes, i.e. when running "make test"? The segfaults occur during the category "70" tests, so during ssl/tls tests for example when testing server - client connections. I only encounter these segmentation faults when using the static libraries instead of the default case with shared libs which confuses me a bit. If you do not encounter these segfaults I guess the error is in my code extensions (patches, added files). Or can there be another reason?
