Hello!

Could you create a ticket about this with all the relevant details (OS X version, boot ghc version, commit, hadrian command, etc), and the 'hadrian' label? You should even feel free to mention @snowleopard and @alp there.

Cheers

I'm trying to isolate the commit that's causing this, but the deal is on MacOS I'm seeing stage1 `ld` crashes linking `HStime`:

A linker snapshot was created at:

/tmp/HStime-1.9.2.o-2019-04-22-132113.ld-snapshot

ld: Assertion failed: (name != NULL), function Fixup, file /Library/Caches/com.apple.xbs/Sources/ld64/ld64-450.3/src/ld/ld.hpp, line 724.
```
I can replicate this on multiple machines and different versions of xcode command line tools.

Any ideas?
