(Sorry for my english)

I am on  ubuntu 9.04

in general i use valgrind to find memory leak into my code, but i continue to have system freeze trying to attaching gdb to valgrind.

i has also tried with example code , also them freeze, i want to know if someone else has the same problem.

To check this


valgrind --db-attach=yes ./MatrixMultiplication

ignoring all "invalid write" and "invalid read"  into the ATI driver, is not a my problem, answering "no" to all question, after few question the system freeze

Someone can test, if has this problem ?
