This is because of __restrict not being accepted by lcc. Defining it to empty fixes the issue.

Could you please introduce the steps more detail? I don't know how to operate. Thanks!

You have to modify the build.sh to keep it from resetting lcc.

I've tried to operate as you said, but the problem still exists. However, when I use movcc to compile my source file by manually adding parameter -D__restrict= and -Drestrict=, it can works.

OK, it works! Thank you very much!

Having this error still. After issue #19 was resolved, if I follow the steps here to fix this error, any binary built with movcc segfaults. Before #19 was fixed, I could follow the steps here and get a working compiler, but I just couldn't use --no-mov-flow. Now, even when not using --no-mov-flow, I'm just getting segfaults with anything I try and compile.

I've tried to fix this, but I can't find the files for the DIFF you're referencing.

[MrAureliusR]

@ThePlasmaRailgun They are in the lcc/ subfolder, except for build.sh which is in the top folder.

[fionafibration]

Ok, I found them, they're in movfuscator/lcc/etc/lcc.c for anyone else looking for them.
