E363 ERROR working with VIM

When i try to edit the byte size file in vim editor iam getting the following error message(OS IBM AIX5.3)
E363: pattern caused out-of-stack error

Anyone know how to overcome this ?.

Its vim specific.(on some aix releases, I knew about 5.1...) .. nothing to do with shell
