coreutils: cannot locate main function
I'm seeing that the cp coreutils sample, and potentially others, fail to locate the main function. This heuristic was changed when initial support for coreutils samples was added, trailofbits/binrec-prerelease#127.
failed to perform initial lifting of LLVM bitcode: s2e-out: Expected a single successor for potential main block, BB_804A030: got 43 successors
I think this is different than the initial regression found that occurs sometimes against binrec samples, trailofbits/binrec-tob#33.
We should verify that this is still an issue after trailofbits/binrec-prerelease#169.
Assigning @jleightcap to verify. If its still an issue then we can try and dig a little deeper.
@michaelbrownuc I believe this is still an issue I'm seeing as a side effect of trailofbits/binrec-tob#14. I was seeing a bad trace info being produced that occasionally was missing the call into main(), which would trigger the bug in this issue.
@ameily Thanks for the update. Is it fair then to say this duplicates trailofbits/binrec-tob#14 now that trailofbits/binrec-prerelease#169 is merged?
@michaelbrownuc I apologize, I really shouldn't comment on anything until coffee is ready.
I just confirmed that this is still occurring, even with the fix from trailofbits/binrec-prerelease#169. I think it is different than trailofbits/binrec-tob#14 since it happens every time. So, I don't think it's a duplicate and most likely we need to make the heuristic for finding main better.
lol no problem, @jleightcap can work on this one once he ramps up a bit on the project (and gets an x86 machine)
