Details:
Hello,
I have this Makefile (attached) and when I run it with -j 8 then I get
random segmentation faults(not always on same point). Running it without -j
option works fine and I do not get segmentation faults all the time (it just
random). My guess is that as I calculate values for some variable only on fly
so may be when run with -j option, two threads try to calculate/access the
same variable and that causes a crash. If I force the calculation of those
variables before any rule to run then it works fine. So may be there is some
variable locking problem.
Cheers,
--Shahzad
