(gdb) p word[w_idx]
No symbol table is loaded. Use the "file" command.
seems as if i have to load a symbol table or something, any hints?

Looks like your libc is broken.
Please type this in gdb after "bt":
f 0
p word[w_idx]
p toupper(word[w_idx])
p isalpha(toupper(word[w_idx]))
and paste the output here

sorry folks you have been right it seems as if the pkgsrc process
somehow stripes debug informations :|. Anyway here is what i got using
a native build process and the native sources (without the latest cvs
patch provided by iliaa)
