Hi Matthias,

can you please verify the test package

python39-3.9.9-3 (not the -2)

$ python3.9 -m sysconfig | grep CFLAGS
         BASECFLAGS = "-Wno-unused-result -Wsign-compare"
         CFLAGS = "-Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv 
-O3 -Wall"
         CFLAGSFORSHARED = ""
         CFLAGS_ALIASING = ""
         CONFIGURE_CFLAGS = ""
         CONFIGURE_CFLAGS_NODIST = "-ggdb -O2 -pipe -Wall 
-Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector-strong
