(You have already found the error, don't you? Wellĭone, but here we learn how to come to the same result using run trace). Program calls each function 33 times, then prints newline and terminates.Īt least in theory. #include void f1(void) įunctions f1, f2 and f3 print letters a, b and c. To make you familiar with the run trace, let's try Pieces of code (without jumps to outside) that should be executed at once.Īnd one more limitation: OllyDbg doesn't save the contents of accessed To accelerate run trace, one can mark quasi-linear On a 500-MHz processor, OllyDbg can trace up to 2500 (Windows 95) or 5000

Please keep in mind, however, that run trace is slow. Ount when command at certain location was executed for the last time, and Limitations or to compare two runs, debug self-modified programs, find Profile traced code, write run trace to disk in order to overcome memory One can set conditions to pause run trace, Run trace shows modified registers and keeps important messagesĪnd operands of known functions. OllyDbg 1.06 has significantly improved the possibilities Several (or hundreds of thousands) last commands and analyse conditions Step, and debugger protocols every command, together with registers andįlags, in the large circular buffer.

Thisĭebugging technique is basically very simple. Run trace was first introduced in OllyDbg 1.04.
