Comment 3 for bug 1809919

I can't reproduce this. I tried with the firmware I'm working on, and with https://github.com/blacksphere/blackmagic.

platform:

```
$ uname -a
Darwin anaesthetic-mac.local 18.5.0 Darwin Kernel Version 18.5.0: Mon Mar 11 20:40:32 PDT 2019; root:xnu-4903.251.3~3/RELEASE_X86_64 x86_64
```

Since brew deleted the formula in response to this bug report, I'm using this tap to install 8-2018-q4-major:

```
$ brew tap ArmMbed/homebrew-formulae && brew install arm-none-eabi-gcc
$ # this installs https://armkeil.blob.core.windows.net/developer/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-mac.tar.bz2
$ arm-none-eabi-gdb --version

Can you post your firmware.bin? If you can't, can you strip it down and make a test case that you can share? Right now everyone doing embedded dev on OS X is in limbo because this bug scared arm-none-eabi out of homebrew :(
