Describe the bug
Summary:
Periodic (seemingly random) but frequent Segmentation Faults when running code on Ubuntu 22; code is fine on Ubuntu 20 and Windows.
Details:
After upgrading Ubuntu 22; dotnet application results in Segmentation Fault.
A trace shows this appears to come immediately after a socket send message (sendmsg) command with .NET ThreadPool[40301]: segfault at 10 ip 00007fefec22c6b0 sp 00007fefbf7f9f80 error 4 in libcrypto.so.3[7fefec11d000+25d000] in the logs. Note: there are multiple prior successful sendmsg commands; so may more may not be related.
Trace shows it could be related to MD5()
