Application crashing when static linking routing service

I have an application that is statically linking to routing service and some other rti libraries.

I have my build setup to statically link these libraries:

  • librtiroutingservicez.a
  • librticonnextmsgcppz.a
  • librticonnextmsgcz.a
  • librtidlcppz.a
  • librtidlcz.a
  • libnddscpp2z.a

These libraries are be dynamically linked:

  • libnddsc.so
  • libnddscpp.so
  • libnddscore.so

Occasionally the application crashes with a "double free or corruption" error.

I saw from another question (https://community.rti.com/forum-topic/double-free-error-exiting-certain-applications) that this might be due to statically linking the rti libraries.  I am changing the code to dynamically link all the rti libraries but was wondering if anyone has any more information on this.  This crash (so far) has not been reproduceable but will happen occassionally so I'm not sure that changing the linking will actually fix the problem.

This is a backtrace of one core file.  In frame 5 RTIOsapiHeap_freeMemoryInternal () is trying to free memory and I see the "double free" error at frame 3.

Hi Anna,

Sorry for the late response. I was wondering if you were able to get to the bottom of the issue. Please let us know.

Hi Gianpiero,

I ended up linking dynamically to the routing service libraries.  I haven't seen this crash since I changed to dynamic linking but I was never able to find the exact cause of the crash. I suspect something my app was doing that was timing related.

Thanks for the followup.
