build log
I've been using UndefinedBehaviorSanitizer at my day job and found it pretty
useful, so did some brief testing on it with Wine.
Not everything builds (notably loader/ and dlls/ntdll/unix/), but most other
stuff does.
For this issue, just recompiling tools/winebuild is enough to see the issue:
./configure && make -j12
cd tools/winebuild
make clean
make CFLAGS="-fsanitize=undefined" LDFLAGS="-fsanitize=undefined"
cd ../../dlls/avifile.dll16/
make clean && make
tools/winegcc/winegcc -o dlls/avifile.dll16/i386-windows/avifile.dll16
--wine-objdir . -b i686-w64-mingw32 -Wl,--wine-builtin -shared \
  dlls/avifile.dll16/avifile.dll16.spec -m16 -Wb,--main-module,avifil32.dll \
  dlls/avifile.dll16/i386-windows/main.o
dlls/avifil32/i386-windows/libavifil32.a \
  dlls/winecrt0/i386-windows/libwinecrt0.a
dlls/ucrtbase/i386-windows/libucrtbase.a \
  dlls/krnl386.exe16/i386-windows/libkernel.a

tools/winebuild/res16.c:156:5: runtime error: null pointer passed as argument

Seems to affect most win16 dlls, there are a total of 44 occurrences (build log
attached).
