Work environment

Questions	Answers
OS/arch/bits (mandatory)	macOS 12.6 ARM64 (M1)
File format of the file you reverse (mandatory)	MachO
Architecture/bits of the file (mandatory)	ARMv8 64
rizin -v full output, not truncated (mandatory)	rizin 0.5.0 @ darwin-arm-64

Expected behavior

rizin -d $(which rz-ax)
[0x1045d4560]> dg
WARNING: core: Writing to file 'core.93555'
[0x1045d4560]>

Core file should be written and be loadable in Rizin afterwards

Actual behavior

rizin -d $(which rz-ax)
[0x1045d4560]> dg
WARNING: core: Writing to file 'core.93555'
^C

Even doesn't work, only kill -9 <rizin pid>

Generate core file successfully, which can be loaded

It's implemented in "native" debugger plugin, see these places:

• librz/debug/p/debug_native.c in rz_debug_gcore() function
• librz/debug/p/native/xnu/xnu_debug.c in xnu_generate_corefile() function

it's stuck had to kill it, the generated core file is empty 0 bytes.

Strange, it "works" for me on both x86 and arm64. (Meaning it writes out some broken mach-o file at least)
Could you please attach a debugger to it when it is stuck and paste a stacktrace?

[marcograss]

Do you have system integrity protection disabled?

[thestr4ng3r]

Good point, yes it is currently disabled here at least on the arm64 machine.

Though this does not seem to be the relevant point here, after enabling it still goes through:

I just tried another x64 machine on 12.6, it doesn't work there also, on commit 1ed4a3a
