Bug ID: 82413
Summary: -O0 crash (ICE in decompose, at tree.h:5179)
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: babokin at gmail dot com
Target Milestone: ---
GCC trunk, rev 253367, x86_64.
Rev 253307 works fine, so it's a fresh regression.
> cat f.cpp
bool a;
int b;
void c() { b &&a <= 0; }
> g++ -c f.cpp
f.cpp: In function ‘void c()’:
f.cpp:3:21: internal compiler error: in decompose, at tree.h:5179
void c() { b &&a <= 0; }
