Crash: IDA 7.5 SP3 on macOS upon attempted decompilation with blc

[kciredor]

Hi @cseagle,

First of all: thanks for your efforts and releasing blc.

Just downloaded the SP3 release of IDA Pro 7.5, running on macOS Catalina 10.15.7 having GHIDRA_DIR=/usr/local/Caskroom/ghidra/9.1.2_PUBLIC,20200212/ghidra_9.1.2_PUBLIC.

Opened linux binary afl-fuzz to ensure blc still works. Unfortunately it does not. Everything was still fine with SP2. I've tried again using newly built binaries to no avail.

When you start decompilation with blc, IDA immediately shows you it's about te crash (Let it crash vs Continue).

Best,
kciredor

It does not crash.with a random ARM64 binary I've just tried.

Have you compiled the module for SP3 yourself, I don't get this part and which function did you try to decompile?

[kciredor]

Yes I also compiled it myself, this one and your fork as well @alexander-pick ;-)

Opened afl-fuzz MachO 64bit in IDA64 and did not change any defaults. Then on the public main function I press my hotkey to exec blc and it crashes.

[alexander-pick]

Is it just in the main or any other functions too?

[kciredor]

Any, for example just tried _setsid which is only a couple of lines of assembly.
