PR 1237/rtems

  • src/lib/libbsp/shared/bsplibc.c: Add logic to prevent stack creep when interrupts occur at a sufficient rate that the interrupted thread never gets to clean its stack. This patch ensures that an interrupted thread will not nest ISR dispatches on its stack.
  • Property mode set to 100644
