$ uname -a
NetBSD netbsd-7 7.0 NetBSD 7.0 (GENERIC.201509250726Z) amd64

>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
...
g++ -o cryptest.exe -DNDEBUG -g2 -O2 -std=c++11  -Wno-deprecated-declarations -fPIC -m64 -pipe -fsanitize=address -fno-omit-frame-pointer bench.o bench2.o test.o validat1.o validat2.o validat3.o adhoc.o datatest.o regtest.o fipsalgt.o dlltest.o ./libcryptopp.a

>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
