>Description:
When attempting to build games/frotz from pkgsrc, this happens:

$ make
...
cc -O2 -DCONFIG_DIR="\"/usr/pkg/etc\""   -DVERSION="\"2.43\""
-DSOUND_DEV="\"/dev/sound\"" -DCOLOR_SUPPORT -DOSS_SOUND     -O1 -fgcse
-fstrength-reduce -fgcse-after-reload -I/usr/include -o src/common/quetzal.o -c src/common/quetzal.c
src/common/quetzal.c: In function 'save_quetzal':
src/common/quetzal.c:562: internal compiler error: in change_address_1, at emit-rtl.c:1819
Please submit a full bug report, with preprocessed source if appropriate.
See <URL:http://www.NetBSD.org/Misc/send-pr.html> for instructions.

If instead I run "make DBG=-O0" then games/frotz builds successfully.
>How-To-Repeat:
Build games/frotz with defaults.

State-Changed-When: Mon, 13 Apr 2020 19:20:38 +0000
State-Changed-Why:
I have a more useful version of this PR in upstream GCC: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85152
It's more useful because it has a small standalone reproducer.
