I was recently playing with gcc 4.4.1 and trying to implement some simple code using the experimental support for std::thread in GCC. The only thing I found about support for it was passing -std=c++0x to g++ at compile time...which allows it to compile but even the simplest example segfaults when I go to create an instance of the thread class:
Now experience tells me that there must be some other lib to link (although I would hope that the compile would produce at least a warning here or something..) but not sure.
int nRC = 0;
thread t(workFunc, "Foo", 10); // <<== segfaults here
There is nothing remarkable about workFunc() though I think the problem is happening before I get there. The call stack looks like this:
Anyhow, unlike everyone else posting here this is not a rush, nothing is "due" I was just curious and wanted to play with some of the new concurrency functionality...
