Created attachment 42265 [details]
Included source code to the callback function, the .ii file

I am writing a callback function in C++ that will be called from Oracle GoldenGate via the User Exit Function API; hence I don't have the source to the calling program.  The code is linked in as a share lib .so module.

My code (ggpost.cpp) in the attachment is about as simple a shared lib I can create, all it does is create the following lines:

std::string test = "${foobar}";
std::smatch m;
std::regex e ("\\$\\{[a-zA-Z_]+[a-zA-Z0-9_]*}");
bool foo = std::regex_search(test, m, e);
std::cerr << "Foo = " << foo << endl;

When the code is compiled against 7.1.0, and run from Oracle GG, is creates the following :
terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast
Aborted (core dumped)

However, if I compile the same code in gcc 4.9.2, it works fine.  Also I have attempted to construct my own calling program and I cannot duplicate the problem with either compiler.

I have gathered as much detail as I can, but because it required OGG to duplicate the full problem, I'm handicapped providing all the information requested in the submission form.

CUsrText is my attempt to create a local parent program to duplicate the problem, I include it, but it doesn't show the problem.

Below is the detailed writeup, and an attachment is included with the code I can provide.
