Using a wordlist with a line >35 characters causes instability #34

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Configure with --enable-cpu (untested if this still occurs without this 
because I don't have an Nvidia GPU)
2. Use a wordlist that contains at least one line with more than 35 characters
3. Run using this wordlist

What is the expected output? What do you see instead?
Expected no issues
See either a segfault or a "Aborted (core dumped) error

What version of the product are you using? On what operating system?
Version 3.5 with --enable-cpu option, on Ubuntu 10.04

Please provide any additional information below.
Example output, with wordlist containing 36 characters per line maximum:
$ truecrack -t tcFile -w acAlpha.txt -v
TrueCrack v3.5

I tested this again on a 64-bit install of Ubuntu 10.04, still using the 
--enable-cpu option. This time, it crashes at a line with at least 40 
characters.
