https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93658 --- Comment #7 from Peter Bergner --- Here's the minimal test case using options -O3 -mcpu=power8 -fstack-protector-strong: void bar(); char b; void foo (void) { char a; int d = b; char *e = while (d) *e++ = --d; bar (); }

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93658 --- Comment #6 from Peter Bergner --- So we are in an infinite loop in process_address() calling process_address_1(). I've hacked in some code to ICE if we loop for too long and I'm currently using creduce to minimize the test case.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93658 --- Comment #4 from Matthias Klose --- the file from icu 65.1 is built using g++ -v -Wdate-time -g -O3 -fstack-protector-strong -Wformat -Werror=format-security -W -Wall -pedantic -Wpointer-arith -Wwrite-strings -Wno-long-long -std=c++11 -c -o
