>Description:
Encountered during routine testing of Crypto++ on NetBSD platform. This particular test exercises a "release build" of the library under C++11 and Address Sanitizer (ASAN).

$ ./cryptst.sh

>How-To-Repeat:
The issue can be duplicated with a reduced test case:

$ cat test.cxx 
#include <iostream>

int main (int argc, char* argv[])
{
  return 0;
}

$ g++ -DNDEBUG -g2 -O2 -std=c++11 -fPIC -m64 -pipe -fsanitize=address -fno-omit-frame-pointer test.cxx -o test.exe

$ ./test.exe

 This may have something to do with "GCC5 and the C++11 ABI",

 This seems no longer reproducible in current, fix possibly from
 http://mail-index.netbsd.org/tech-userlevel/2016/11/30/msg010386.html

State-Changed-From-To: open->closed
State-Changed-By: maya@NetBSD.org
State-Changed-When: Sun, 18 Aug 2019 05:30:18 +0000
State-Changed-Why:
ttest case now works, and address sanitizer has seen a lot of improvements in general, assuming fixed. thanks for the report!
