[llvm-dev] lld does not build

Wed Jan 15 02:54:20 PST 2020

That's a crash in the compiler you are using, not a problem with lld, so
I'd suggest following the instructions at the end of the crash report, and
contacting support-hpc-sw at arm.com.

It looks like the crash is happening during an optimisation pass, so you
could try compiling at a lower optimisation level (replace -O3 with -O0 or
-O1) as a workaround for now.
