[PATCH] scripts/bloat-o-meter: fix SIGPIPE

From: Alexey Dobriyan
Date: Fri Oct 28 2016 - 14:46:54 EST


Fix piping output to a program which quickly exits (read: head -n1)


$ ./scripts/bloat-o-meter ../vmlinux-000 ../obj/vmlinux | head -n1
add/remove: 0/0 grow/shrink: 9/60 up/down: 124/-305 (-181)
close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr
