Re: [RFC] New compression function.

[Hideki IWAMOTO]

Hi. Yamaguchi san.

I found a problem about GTAGS_COMPNAME.
When GTAGS_COMPNAME is set and GTAGS_COMPACT is not set, calling like
compress("foo::bar","bar") causes NULL pointer access in the following line. 

  203                         int i, limit = name2ab->length;

How should this be fixed?
