internal error in asm module(quartus 11.1 sp2 /13.0/14.0)

Hi there,

Recently I suffered a lot from quartus II internal errors.

The error always happened in ASM module. I have tried

delelted db/incremental_db directories but it did not help.

I have tried different version quartus and it always happens.

Sometimes it disappears if I change fitter option, however

it reports error after I make several times compilation.

Below is the error reports in quartus 14.0, hope someone

have a solution. Thanks a lot!
