Closed zxpan closed 7 years ago

zxpan commented 7 years ago

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

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 commented 7 years ago

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