Add a regression test that reproduces the SyncChangeCounter use-after-free. The test creates a counter (value=0) and issues SyncAwait with two conditions on the same counter, both waiting for value >= 1. A second client then calls SetCounter to set the value to 100. SyncChangeCounter iterates triggers; the first fires and FreeAwait frees all sibling trigger list nodes via SyncDeleteTriggerFromSyncObject. Without the fix, the saved pnext pointer would dangle, and the next iteration would dereference freed heap memory.

X server test suite This suite contains a set of tests to verify the behaviour of functions used internally to the server. = How it works = Through some automake abuse, we link the test programs with the same static libraries as the Xorg binary. The test suites can then call various functions and verify their behaviour - without the need to start the server or connect clients. This testing only works for functions that do not rely on a particular state of the X server. Unless the test suite replicates the expected state, which may be difficult. = How to run the tests = Run "make check" in the test directory. This will compile the tests and execute them in the order specified in the TESTS variable in test/Makefile.am. Each set of tests related to a subsystem are available as a binary that can be executed directly. For example, run "xkb" to perform some xkb-related tests. == Adding a new test == When adding a new test, ensure that you add a short description of what the test does and what the expected outcome is.
