I'm also not able to reproduce, but I see a different linker invocation:
g++ -shared -static-libgcc -o sourceCpp_3.dll tmp.def file43185fe94049.o
-LC:/rtools43/x86_64-w64-mingw32.static.posix/lib/x64
-LC:/rtools43/x86_64-w64-mingw32.static.posix/lib -LC:/R/R-43~1.0/bin/x64
-lR
In particular, yours is passing both '-std=gnu++17' and '-s'. Have you
modified your R Makevars file, or R installation's etc/Makeconf?
