Creating rpm built distributions fails with error "fiosynth-3.5.39.tar.gz: No such file or directory" about fiosynth HOT 2 CLOSED

the tar file is present at ./build/bdist.linux-i686/rpm/SOURCES/fiosynth-3.5.39.tar.gz and not ./build/bdist.linux-i686/rpm/bld/fiosynth/fiosynth-3.5.39.tar.gz

from fiosynth.

The issue is with rpm-build v4.14.3. With rpm-build v4.11.3, I could create rpm.
