Re: [reSIProcate] Different versions of libresiprocate.a in the same executable

Hi,

I have a binary that loads up two shared libraries (.so). The first .so
has been statically linked with an older version of libresiprocate.a
(more than a year old). The second .so has been statically linked with a
recent version of libresiprocate.a (about 2 months old). (Both of them
instantiate SipStack, but use different port numbers)

When I start up the binary, I get a core dump, backtrace is given here.
If I load just one .so at a time, then things are ok.

My question is: Why could this be happening? How do I debug and fix it?
Has anyone tried this sort of setup?

Thanks for your help in advance,
Sandeep

Sandeep;

I think a good question for you might be:

What are you trying to accomplish, and
What are your requirements?

The scenario that you describe is NOT a safe use of a library that has static / singleton design patterns. C++ does not provide support for this sort of things, so the API of the library you want to use in this fashion needs to help you accomplish it. In particular, the ABI needs to be stable or self- correction. reSIProcate is neither over the period you describe.

Perhaps if you tell us your goals, we can propose an alternate strategy or a viable enhancement for the stack, if one exists.

Cheers,
