mkimage segfault on MacOS

[Alexander von Gluck IV]

I know this one is pretty far out there (and not expecting a solution here tbh),

mkimage (installed via homebrew) is segfaulting under MacOS X (10.15.3)

 $ mkimage -A arm -O linux -T kernel -C none -a 0x1000000 -e 0x1000010 -n 'Haiku arm loader' -d objects/haiku/arm/release/system/boot/u-boot/boot_loader_u-boot haiku_loader.u-boot
Segmentation fault: 11

I went through all the hoops to get gdb working (https://gist.github.com/gravitylow/fb595186ce6068537a6e9da6d8b5b96d) (https://gist.github.com/gravitylow/fb595186ce6068537a6e9da6d8b5b96d),
but homebrew doesn't include debug symbols in mkimage :-|

(gdb) run -A arm -O linux -T kernel -C none -a 0x1000000 -e 0x1000010 -d objects/haiku/arm/release/system/boot/u-boot/boot_loader_u-boot haiku_loader.u-boot

I need to install linux once the Apple T2 chipset driver is upstreamed. :-)
Mostly posting this here as an FYI for any future folks who run into it.
