"red zone" below the main stack in order to protect other stacks. The size of the main stack is determined by the _thr_stack_initial variable that is declared extern though it doesn't seem it can be changed. The value of the variable is set to 4M on 64-bit platforms which is obviously not sufficient for the most of real programs. Can anyone please confirm that there is no way to increase the stack size for the main thread and thus any program linked against libthr has only a few megabytes of stack memory for its main thread--whatever the system stack size (ulimit -s) is set to? Thanks. --
