I haven't tested this, but from my investigation, you should be alright. Sohail
I have verified that wrapping static mutex object around serialization methods work. The performance degradation is quite noticeable though. Fei Andrej van der Zee wrote:

Agreed. Atleast Robert has plans to fix it which is good. I believe gcc has the concept of threadsafe statics where dynamic initialization is protected by a mutex so atleast there you should be safe. Sohail
Cheers, at least I will be safe then ;) Though, I think there should be a (big) warning on the web-site, might safe some time and frustration for other users. Currently it sais "There are currently no known bugs". Furthermore, I think it is a great library, especialy the seamless intergration with boost/variant and smart_ptr :) Thanks for the info, Andrej --- Sohail Somani <s.somani@fincad.com> wrote:
