Test case (same as gcc.dg/guality/pr45882.c)
A number of gcc.guality tests like gcc.dg/guality/pr45882.c fail on aarch64
when compiled with -flto. The tests work when compiled with -O0 -g or with -O2
-g, but fail with -O2 -flto -g.
I have attached the source of gcc.dg/guality/pr45882.c to this test, if you
compile it and debug it and give gdb the following commands:
break 16
run
print e
quit
gdb will print 142 when debugging a program that was compiled without -flto
and 0 when debugging a program compiled with -flto.
