lupdate 4.3.0 does not work but 4.2.2 works?!

Is the behaviour identical if you create an new .pro file containing only TRANSLATIONS lines?

No.

TRANSLATIONS = test_de.ts \
               test_en.ts

TRANSLATIONS = test_de.ts \
               test_en.ts

To copy to clipboard, switch view to plain text mode 

C:\test>lupdate test.pro
Updating 'test_de.ts'...
    Found 0 source texts (0 new and 0 already existing)
Updating 'test_en.ts'...
    Found 0 source texts (0 new and 0 already existing)

C:\test>lupdate test.pro
Updating 'test_de.ts'...
    Found 0 source texts (0 new and 0 already existing)
Updating 'test_en.ts'...
    Found 0 source texts (0 new and 0 already existing)

Ok, so this suggests something in the .pro file corrupts the behaviour of lupdate. Maybe some non-printable character or something like that?
