Description mcermak 2025-05-28 16:07:56 UTC

The `make ltpchecks` target reports a failure in the munmap03 test case. This failure occurs because the test triggers Valgrind to log warnings such as:

==292328== Warning: client syscall munmap tried to modify addresses 0xffffffffffffffff-0x1ffe

Since the tests are run with the -q (quiet) flag, warnings like this should ideally be suppressed. The attached patch ensures that these messages are hidden as expected.

Looks correct for -q. Since this is a generic handler I also removed the Warning from the {freebsd,solaris}/scalar.stderr.exp files since those tests are run with -q.

    Hide "client tried to modify addresses" warnings when -q (quiet) is set
    
    When -q is set, that is when verbosity is 0, the "client tried to
    modify addresses" warning should be hidden.
    
    Also remove the warning from {freebsd,solaris}/scalar.stderr.exp
