Read access to std::map from multiple threads

[mathieu]

hi there,

  I am currently having some very random seg faults. The few times
where it seg fault this is somewhere during a read access to a
std::map. Those accesses are concurrent (SMP machine). Is there
something I need to do even for read only access ?

  thanks
