            Bug ID: 61609
           Summary: running libraries compiled with different gcc versions
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gnu.org at hovland dot cx

I have an application that tried to access a C++ class that was compiled into 2
different .so/library files. This class uses std::mt19937 and
std::uniform_int_distribution

When only the first library was compiled with GCC 4.9.0, the application
segfaulted.
When I compiled the second library with 4.9.0 also, the application didnt
segfault any more.

The first library was compiled with GCC 4.7.2
I'm not sure if this is a bug in GCC or its supposed to be like that. It would
be great if it didn't segfault this way since I would have to recompile all my
libraries then.

I unfortunately don't have the coredump
