Quartus II Problem Report: The Quartus II software quit unexpectedly

I have managed to crash Quartus by trying to synthesise my Cyclone V project. 13% through the 'Fitter' phase a pop-up indicates the message in the title.

When I click on 'Search for a solution' it searches for the following string within the Altera website:

'internal error: sub-system: cclk, file: /quartus/periph/cclk/cclk_gen5_base.cpp, line: 5538'

Anyone seen this before?

Thanks in advance,

Robbie.

    I have recently faced the same crashing problem using quartus 15.1

    I was using LVDS serdes and put two LVDS_RX on the same input pins and two LVDS_TX on the same output pins.

    When I removed the duplicate blocks, the compilation flow did not crash.
