Quartus_map ended unexpectedly

[Altera_Forum]

My design contains one alt_pll with 6 enhanced clock and one altpll_reconfig. When I try to synthesis my design I have an error : 

 Error: Current module quartus_map ended unexpectedly ------------------------------------------------ invalid command name "qcu_get_design_name(char"  while executing "unknown_original qcu_get_design_name(char const*)+0x3 +0x92c1988 (quartus_map)"  ("eval" body line 1)  invoked from within "eval unknown_original $cmd $args"  (procedure "::unknown" line 5)  invoked from within "qcu_get_design_name(char const*)+0x3 +0x92c1988 (quartus_map)"  invoked from within "execute_flow -compile"  (file "demo.tcl" line 25)   I have no idea, how to correct my problem ?

Could you post more details about the error? For example, attach a Quartus Archive file of your project so other ppl can try to reproduce your error and then help you.
