--- Comment #5 from Dr. J=C3=BCrgen Sauermann <bug-apl at gnu dot org> ---
Hi,

above is one preprocessed source file for which the warning has occurred. g=
++
version was 11.0.0 (latest from github).=20

Compiled with:

g++ -E -DHAVE_CONFIG_H -I. -I..    -Wall -I sql -Werror -I/usr/include
-I/usr/include/postgresql   -rdynamic -g -O2 -MT apl-Bif_F12_FORMAT.o -MD -=
MP
-MF .deps/apl-Bif_F12_FORMAT.Tpo -c -o apl-Bif_F12_FORMAT.cxx


Interestingly, if I compile the file apl-Bif_F12_FORMAT.cxx separately (with
-Wall) then the warning does not show up.

Not sure how I can create a testcase file other than preprocessing or
minimizing it.=
