但是，我没有阅读核心转储的专家 - 我已经阅读了一些帖子，例如How to analyze a program's core dump file with gdb?和https://httpd.apache.org/dev/debugging.html，但我不太确定下一步。
我应该假设我的OpenSSL库出现了问题，我应该重新编译吗？还是我错过了别的什么？欢迎所有反馈！
答案 0 :(得分：1)
我应该假设我的OpenSSL库出现了问题吗？我应该重新编译它吗？
最有可能。
您正在使用/usr/local/openssl/lib/libcrypto.so.1.0.0，我认为这不是您的发行版附带的版本。
您似乎没有编译此库以供线程使用，但您的Apache 使用来自多个线程的库，从而触发断言失败。
This是我在assert内找到的唯一ssleay_rand_add，它只在!defined(OPENSSL_THREADS)时编译，我认为这对你的构建是正确的，并且是./Configure no-threads ...的结果。
您应该使用./Configure threads ...重建libcrypto.so。 Documentation
