+ c/src/lib/libc/support/generic/malloc.c did not initialize the
    sbrk amount
  + _Thread_Handler in c/src/exec/rtems/thread.c left a window
    during the begin extension which could result in a context switch

fixed places which did not correctly distinguish between an
CPU_isr and a CPU_isr_entry.
