What steps will reproduce the problem?
1. Start with mint client
2. when making probe, set "all" entries in jmpbuf to random values
3. run example code.

What is the expected output? What do you see instead?
Full execution of example code.
Program will fail with "No Thread Launch" error.

What version of the product are you using? On what operating system?
Product revision 31. Windows 7 64bit.

Processor: AMD Phenom II X4 910
Architecture: AMD64

FIX:
Can be fixed with initializing all probe members to 0.

Message to Author:
Thanks so much for this library! It's a great way to start learning about 
coroutines and a good spring board for future projects.

What steps will reproduce the problem?
CVS checkout on OS X Leopard 10.5.5
make

gcc -ansi -pedantic -O2 -fPIC -I./ -c libconcurrency/coro.c -o
libconcurrency/coro.o

On  a Macbook (intel core 2 duo)

What steps will reproduce the problem?
1. Open project in Visual Studio 2013
2. Set project configuration as "Release"
3. Run example code.

What is the expected output? What do you see instead?
Program should complete successfully. Example crashes on switching to a saved 
coroutine.

What version of the product are you using? On what operating system?
Using revision 2013 on Windows7 64bit.

I don't think the setjmp logic works at all.  longjmp will always stay inside
coro_call() because there's also the setjmp that goes with it.
setjmp doesn't record the stack of the previous frame but the current one; and 
that's coro_call().
