Wt

I am having crashes when using WRandom after a call to ACE::daemonize.

It is probably due to the fact that in WRandom.C, line 53, there's a static instance of RandomDevice. Which in it's default constructor, initializes boost::random_device rnd.

After a fork, this structure is corrupted and if you attempt to access it you get the following exception:

boost::random_device: error while reading random-number pseudo-device /dev/urandom: Bad file descriptor

If there are other static instances there's a chance that other issues.

It would be fine if it was lazy initialized.

It works fine if I don't daemonize, or if I modifiy WRandom.cpp to not use boost.

Using Wt 3.1.8, gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 and ACE 5.7.1.

I attached an example of the issue.
