Re: [rtl] rtl pthread bug ?? (was unwelcome reboot)

Olaf,

1. To fix problems with rtl_printf buffer overflows, you need to upgrade
to version RTLinux 3.x. 3.0pre8 is the latest.

2. The real problem with the code is that Linux does not have a chance to run:
your thread2_code never blocks. Insert usleep(100000) in the loop and it should
work.
