Quartus 11.0 Assembler Crashes

I synthesized a design. I then run the following command to generate an RBF file from my SOF:

C:/apps/altera/11.0/quartus/bin64/quartus_asm design_name -c design_name

I get the following stack dump:

I have tried the 64-bit and 32-bit version. I have tried command line and gui. I have tried rebooting. I have tested with Quartus 8 and 10.1 and they both work fine. All my licenses are up to date and working. I am running Win7 64-bit.
