hashcat crashing when trying to crack longer passwords

[droidman]

you know there is a big difference between a controlled abort and a crash. what is it doing?

when i press S for status it crashes.


what it says on that image is Portuguese for:
cudahashcat has stopped working
windows is searching for problems... etc
if i dont press S for status it takes a long time and then crashes.
with up to 9 chars, works, more = crash.
im on windows 7 enterprise 64 bit 16GB of ram and a i5 processor.
everything else works. if someone has a full 12 char WPA2 wordlist with this charset it would also fix my problem:
1234567890abcdef
(only 12 char)

thank you for your help
