I am trying to test the changes to the gpe plugin using msynctool.
When I use msynctool --discover, I get a "double free" crash in the opensync IPC code. Note: so far the only GPE plugin code that has been called is get_sync_info (which has been called twice). I presume this IPC code is about to call my initialise routine but it crashes before it can.
The error message is:
*** glibc detected *** /vranx-linux/home/Linux/opensync/build2/bin/msynctool: double free or corruption (fasttop): 0x000000000073b5e0 ***
The gbd backtrace shows:

I will attach the two trace files generated during this test.
