mid_kidI ended up using GDB, and `watch`ing the memory it read the value from. Turns out, the most significant half of a pointer is written to the variable that's used to decide the jump.But why does that pointer location differ between the host and QEMU? Well, the area is allocated through malloc(). When you malloc big enough chunks of memory, <a href="https://fosstodon.org/tags/glibc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glibc</a> will allocate it using the kernel's mmap() system call, and let the kernel deal with it.(cont...)<a href="https://fosstodon.org/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a> <a href="https://fosstodon.org/tags/Debugging" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Debugging</a> <a href="https://fosstodon.org/tags/ReverseEngineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ReverseEngineering</a> <a href="https://fosstodon.org/tags/lowlevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lowlevel</a>

mid_kidThis allowed me to start patching jumps to always take one specific decision (or patch the entire function out), bringing the instruction logs closer together.And now I found the specific jump that causes the differing output. Next step will be figuring out how to get <a href="https://fosstodon.org/tags/gdb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gdb</a> to breakpoint on the exact differing jump, and try to trace the decision back to its origin data.Does anyone have any tips on tools to follow data through a program?<a href="https://fosstodon.org/tags/Debugging" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Debugging</a> <a href="https://fosstodon.org/tags/ReverseEngineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ReverseEngineering</a> <a href="https://fosstodon.org/tags/lowlevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lowlevel</a>
