Hi,
I am prety new to valgrind. I mainly use memcheck, sgcheck and massif.
As I want to check stack and heap memory usage of a binary I use massif and
found something weird to me :
I used `valgrind --tool=massif --time-unit=B --peak-inaccuracy=0.1
--threshold=0.1 --detailed-freq=1 --max-snapshots=1000
--massif-out-file="my/math/massif.out" my_binary to get a heap profile. The
last snapshot was the following :
--------------------------------------------------------------------------------
n time(B) total(B) useful-heap(B) extra-heap(B)
stacks(B)
--------------------------------------------------------------------------------
747 1,828,928 0 0
0 0
So all was fine. Then I tryed with --stacks=yes and got this :
--------------------------------------------------------------------------------
n time(B) total(B) useful-heap(B) extra-heap(B)
stacks(B)
--------------------------------------------------------------------------------
856 78,076,000 2,256 1,040 8
1,208
I don't understand why this time the useful and extra heap does not fall to
0 even if it is the same binary.
Some explanation would be very helpful and welcome :)
Regars.
