[Bug general/5869] New: can't print contents of a C string

[tromey at redhat dot com]

I have a "const char **" in my program.  I tried to print the
string but couldn't figure out how to get fhpd to print the contents

(fhpd) p pfilename
(const char **) 0x8b2797c
(fhpd) p *pfilename
(const char *) 0xbf8af822

The "const" is likely throwing it vis:
