Fail to load DB of GCC source

[vivanishin]

I am trying to build/load database for the gcc source code. The error manifests in both cases:

• trying to load a cscope DB ( :CCTreeLoadDB [./cscope.out])
• trying to load a ccglue DB (:CCTreeLoadXRefDB ./ccglue.out)

Error detected while processing function 367..345..346..253..254..255..279..280:
line    3:
E119: Not enough arguments for function: 289
E15: Invalid expression: s:CCTreeSym.mCreate("")

There is an empty symbol "" in the cscope db file. Are you using the standard cscope distribution?
