multi threaded program debugging

[calanor]

Hi, I am new to multi threaded programming and it seems debugging them is really really hard Can anybody point me to a good tutorial or book on it. Most of the tutorials I came across were really short and inadequate.

Define a trace macro which dumps the line number or a bread-crumb name when it's entered. You could also have it dump the thread id with it. You can dump these to std cout or via printf whatever.

This way you can collect the paths.
