Just a wild guess: Could this be caused by the bug discussed
recently which leads to stack overflows when interrupts
occur too frequently?

If the program uses printf() (or any other output to stdout)
extensively, the UART will probably generate a high interrupt
load and might trigger a stack overflow.
