That is 10gic's Vanitygen-plusplus right?
Tip for that fork: For real-world usage, use

Example:
./oclvanitygen++ -F compressed 1BANANA

It's not supposed to end in a segfault.
It was my first time using it, so I'm not familiar with the errors and stuff. Will you kindly tell me what went wrong or the cause of this?

"
SegFault" is so generic that you'll never know the cause without looking at logs, code and OS to pinpoint the cause.
