nope, nor does:
if( (unsigned)(*endname + 1) > 256 || !isspace(*endname) && *endname != 
'\\' && *endname != '/' )

the problem just gets postponed and eventually someone tries to access 
0xfdfdfdfd

however, changing the malloc back several lines to be one larger, then 
putting a '\0' at the end _does_ seem to fix it.

Checked into CVS.
