Fixed Release: None
_______________________________________________________
Details:
I have a simple Makefile:
base = xxx-$(shell date '+%Y%m%d-%H%M%S')
t:
@echo $(base)
@echo $(base)
@echo $(base)
@echo $(base)
@echo $(base)
@echo $(base)
Sometimes when I 'make t' from the shell, the value of $(base) changes:
$ make t
xxx-20060825-222523
xxx-20060825-222523
xxx-20060825-222523
xxx-20060825-222523
xxx-20060825-222524
xxx-20060825-222524
This only happens rarely, perhaps once every 20 runs. I'm on Mac OS X 10.3.9
running a freshly built make 3.81. I can put some @sleep 5 lines into the
above t target and still see the same thing happen.
