Summary: ICE when building xmrig on AArch64
Product: gcc

Status: UNCONFIRMED
Severity: normal
Priority: P3

Preprocessed source file
When building xmrig on AArch64 with GCC 9.3.1, this file will trap cc1plus into
infinitely running.
I extracted the preprocessed source and then proceed with GCC master (commit
0a74a0e1a2d ("libstdc++: Fix custom clock in test")), and now it fails with
ICE:
