+commit a4927ebffae000198f6054eea26191ac2e50697f
+Author: Tom Lane <tgl@sss.pgh.pa.us>

+
+    Use BIO_{get,set}_app_data instead of BIO_{get,set}_data.
+    
+    We should have done it this way all along, but we accidentally got
+    away with using the wrong BIO field up until OpenSSL 3.2.  There,
+    the library's BIO routines that we rely on use the "data" field
+    for their own purposes, and our conflicting use causes assorted
+    weird behaviors up to and including core dumps when SSL connections
+    are attempted.  Switch to using the approved field for the purpose,
+    i.e. app_data.
+    
+    While at it, remove our configure probes for BIO_get_data as well
+    as the fallback implementation.  BIO_{get,set}_app_data have been
+    there since long before any OpenSSL version that we still support,
+    even in the back branches.
+    
+    Also, update src/test/ssl/t/001_ssltests.pl to allow for a minor
+    change in an error message spelling that evidently came in with 3.2.
+    
+    Tristan Partin and Bo Andreson.  Back-patch to all supported branches.
