[Valgrind-users] Valgrind 3.8.1 DRD stuck

[Young Wn S. <you...@ya...>]

Hi,

I was using Valgrind 3.8.1 DRD on Parsec 2.1 Benchmark suite.

x264 program in Parsec runs for more than few hours and does not stop.
I know it takes long time but the previous version 3.7.0 DRD finished the same program in 300 seconds.
(I also tried to stop using Ctrl + c and Ctrl + z to suspend but that does not work to stop it either.)

Do you have any idea?

Environment:

Intel Core 2 Duo CPU
Ubuntu 12.04

gcc 4.6.3

The exact commnad line used including Valgrind DRD and program parameters:
valgrind-3.8.1/bin/valgrind --tool=drd --first-race-only=yes --read-var-info=yes -v ./inst/i686-linux.gcc-pthreads/bin/x264 --quiet --qp 20 --partitions b8x8,i4x4 --ref 5 --direct auto --b-pyramid --weightb --mixed-refs --no-fast-pskip --me umh --subme 7 --analyse b8x8,i4x4 --threads 2 -o eledream.264 ./inputs/eledream_640x360_128.y4m


Thanks.
