Hi Daniel

Thanks for the reply.

I put it through Valgrind and it came out ok. The nice thing was that it gave me a reason to build a test app for CentOS (the results from Valgrind in mac-os was really confusing).

Finally I managed to find it out with a bit of persistence and some luck. The error seems to have been caused by that in some very rare conditions 2 worker threads was created. With some minor pthread fixes and assuring that curl was only started and stopped with the complete lifecycle of the app, the problems went away. There are some extremely rare crashes around resolve failures but we are talking about 10 in total over the last 5 days so its nothing and I also have no info to go on.

In general it looks good now, a real pleasure using curl so far.

Have a nice vacation and thanks for all the help

Johan
