Bug ID: 71478
Summary: ICE in tree-ssa-reassoc.c after r236564
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: jgreenhalgh at gcc dot gnu.org

Target Milestone: ---

Reduced testcase
I took a look at PR71170, PR71230, PR71252 and PR 71281, but they seemed subtly
different to my issue.
The attached testcase fails for me on trunk with -O1 on
x86_x64-unknown-linux-gnu and aarch64-none-linux-gnu.
The ICE looks like:
x.c: In function 'foo':
x.c:7:1: internal compiler error: gimple check: expected
gimple_assign(error_mark), have gimple_call() in gimple_assign_rhs1, at
gimple.h:2493
foo (void)
