MacOS Mojave: pdftoppm removes bold fonts

Conversion with Preview: everything looks good:
Conversion with pdftoppm
pdftoppm -singlefile -rx 100 -ry 100 -png testigureR_boldfont.pdf testigureR_boldfont.pdf
pdftoppm version 0.77.0 On the most recent MacOS I installed poppler brew upgrade poppler
On another machine with macOS 10.12 everythings is ok. Any suggestions why this happens and how to resolve this are welcome!
