invalid pointer in running tests

[zxpan]

I am running the tests with this commit 779a693f59ae41dcef5fb2760d1fe982a56e7349, observed following errors:

  Start 20: WdtOverwriteTest

*** Error in `./_bin/wdt/wdt': free(): invalid pointer: 0x00002b86c4000930 ***

*** Error in `./_bin/wdt/wdt': free(): invalid pointer: 0x00002b9a18000930 ***
20/23 Test #20: WdtOverwriteTest .................***Failed 14.11 sec

Would like to bring your attention if this is indeed an authentic issue.

My environment: Ububtu 14.04, g++-4.9

which version of openssl are you using ?
can you run with asan maybe ?

[zxpan]

I am using "OpenSSL 1.0.1f 6 Jan 2014".

Sorry for the delay, we've been busy.

Can you upgrade your openssl to 2016-Sep-22 10:35:26 openssl-1.0.1u
all earlier versions have serious security and other bugs

and confirm that fixes the crash?
thanks

[ldemailly]

please reopen if the upgrade didn't solve it or if you have any further problems
