Still Failing: openssl/openssl#24825 (OpenSSL_1_1_1-stable - 18111b1)

[Travis CI]

Build Update for openssl/openssl
-------------------------------------

Build: #24825
Status: Still Failing

Duration: 25 mins and 32 secs
Commit: 18111b1 (OpenSSL_1_1_1-stable)
Author: Richard Levitte
Message: asn1parse: avoid double free

|str| was used for multiple conflicting purposes.  When using
'-strictpem', it's used to uniquely hold a reference to the loaded
payload.  However, when using '-strparse', |str| was re-used to hold
the position from where to start parsing.

So when '-strparse' and '-strictpem' are were together, |str| ended up
pointing into data pointed at by |at|, and was yet being freed, with
the result that the payload it held a reference to became a memory
leak, and there was a double free conflict when both |str| and |at|
were being freed.

The situation is resolved by always having |buf| hold the pointer to
the file data, and always and only use |str| to hold the position to
start parsing from.  Now, we only need to free |buf| properly and not
|str|.

Fixes #8752
