These posts are not on topic. You're hitting many basic C++ errors and this list is not the place to learn the language. Refer to for details.

In this case, you're never advancing through textBuffer->buffer's elements but rather calling front() repeatedly. You need to call pop_front() to move to the next element. I have no idea what outPutText is, but it may be misbehaving when you make it too large.

For that to segfault, I suspect your memory is trashed. Is textBuffer still a valid pointer in that case? Have you actually used a debugger?

Please consider posting to comp.lang.c++.moderated or somewhere else to work on such problems.
