... And it continues to #1. Does the above output mean that several memory addresses are being written to that do not exist?

To me it looks like your stack is trashed.

0x52455600 is REV (or VER)
0x41434954 is ACIT (or TICA)
0x4f465f4c is OF_L (or L_FO)
0x2f2f6769 is //gi (or gi//)
0x65766173 is  evas (or save)!
0x65746152 is etaR (or Rate)!

Most of the remaining addresses seem to give nice ascii characters.

You might have overflown a buffer.

---

It means the debugger have no clue what those memory addresses are. This could be because debugging information is missing for the stuff you're debugging - e.g. inside a library that doesn't have debug information.

Though seeing such a long trace usually means you've smashed the stack, overwritten information the debugger needs, lead your program so far astray neither the debugger nor the program have any clue left as to what's going on. (i.e. you've a buffer overflow somewhere, fire up valgrind and try to find it)
