Qt Creator crash when loading project using $$system(date /t)

My project has many subdirs (a total of 140 .pro files). Every .pro file for a exe or dll uses a certain central prf file (either direct by CONFIG += my_init, or indirect by another prf file including it by load(my_init.prf).

When using $$system(date /t) in my_init.prf, Qt Creator will crash very often while loading the project (say 9 out of 10 times).

Crash info from windows event log:
