https://bugzilla.redhat.com/show_bug.cgi?id=1368855 --- Comment #43 from Anton Kochkov <anton.kochkov@xxxxxxxxx> --- (In reply to Elliott Sales de Andrade from comment #42) > 3.0.5? It was released today; no need for bundling. Just ping the maintainer > about it. Problem is that 3.0.5 is a release of a "stable" branch, which is not the one required for radare2. There is also a "next" branch with more architectures and instructions support. It will be released as a 4.0 version, which is awaited for years. Having an updated disassembly engine is vital. Let me illustrate it by example. x86 platform has a variable instruction size, thus if we decoded some instruction wrongly the rest of disassembly (at least for some period, like 10-40 instructions) will be totally wrong. There was a recent bug in latest Fedora, where compiler started function prelude with "endbr64" instruction, which wasn't recognized by capstone at all, thus leading to the wrong disassembly and fail to analyze function boundaries and creating one. Because this is the "main()" function it completely broke further function analysis too. Just because of one instruction https://github.com/radare/radare2/issues/10113 r2 fedora28_bin_ls -- Welcome to IDA 10.0.
