[fpc-pascal] Error: Internal error 2014052302 on changing some common units

[Dennis]

whenever I change the source of a common unit (that is used by many 
other units), when I compile with lazarus 1.7 +FPC 3.1.1, this error 
will appear in the messages
"Error: Internal error 2014052302".

What is that?

Normally, I just go to Menu -> Run-Build and this message will disappear 
but this process is slow and I try to avoid it.

Any idea ?

Dennis
