I wasn't able to reproduce the issue. I've tried the attached reproducer but:
- I don't have a file "TrustStore.pem",
- if I comment out the block of code that tries to load this file, I get
"Certificate verification error: 20",
- in both cases, valgrind reports no memory lost or still reachable.
I'll mark this bug as Incomplete.
** Changed in: openssl (Ubuntu)
Status: New => Incomplete

Title:
Memory leak in libcrypto.so\libssl.so
Status in openssl package in Ubuntu:
Incomplete
Bug description:
I've found a bug in openssl 1.0.1-4ubuntu5.10. Was trying to use
libpq\libmysql.so to connect to database and did not specify sslmode
so it used ssl to connect to database, when i've checked with valgrind
i've detected some memory leak:
