Bug ID: 398445
Summary: uninitialized memory false reports on shared memory
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: memcheck

test case
Hello.
The attached test-case demonstrates the problem.
It creates 2 pages of shared memory, uninitializes
one page and initializes another. Even though both
pages contain valid values, valgrind doesn't understand
shared memory and reports an error.
I have the program that uses shared memory a lot,
and gets hundreds of false errors from valgrind.
