exim fails disassembly #22

Closed jrmuizel closed 3 years ago

jrmuizel commented 3 years ago

exim compiled with icc-19.1.1.219 fails with:

ddisasm ./exim --asm exim.s
Building the initial gtirb representation  (118ms)

The --layout option to gtirb-pprinter can fix overlapping elements.

The conflicts between the following code blocks could not be resolved:

Aborting

This is with ddisasm 1.4 (1cbb62c)

I've attached the binary exim.zip

I ran into this while trying out ddisasm on https://github.com/pangine/disasm-benchmark

I tried running it with the latest master (daa0ab84960925d64fcf6c5c2ddb4462a392e50f), and found it worked fine. It is highly likely that it got fixed at some point last couple months.
