I'm pretty rusty, but I've run into something that I don't understand.
for( str = vimvars[VV_GETCHARTYPE].vv_str; *str != NUL ; str++ )
*str = tolower( *str );
In gdb, it tells me "cannot access memory at address ...." whenever I
try to set to *str.
The memory at
vimvars[VV_GETCHARTYPE].vv_str
seems to be a simple alloc(). The string was created with
vim_strsave(), but I can't find anything special in that either.
The vimvars or vv_str structure is too comlex for gdb to manipulate directly
print vimvars[50].vv_str
says "There is no member named vv_str.", so I've run out of ideas why
a specific memory address is protected(?) even though it is readable
(print str shows the correct string).
The string was created with vim_strsave(), but I can't find anything
special in that either.
I can go through the vim_free() and vim_strsave() again, but it seems
unnecessary, and the real point is, "WTF?" :-)
