Hi Fred, Sorry for the delay in replying. If you're using the --wrap option for your own symbols (which is the common case), I'm sure there's no conflict.
If you should also want to write a wrapper around a system call (around a function from libc.so, libpthread.so, etc.), then it should work, but we haven't done much testing in this case. If you find a problem here, please tell us, and we'll fix it. Also, an easy way to write wrappers around system calls is to use the DMTCP plugin facility (formerly called DMTCP modules). DMTCP version 1.2.5 should appear "any day now", and will use the new "plugin" terminology. For more information, see: http://dmtcp.sourceforge.net/FAQ.html#plugins (In DMTCP-1.2.3 and DMTCP-1.2.4, the directory was called 'module'.)
