/* This test checks that the dynamic linker correctly logs thread creation
|
|
and destruction. It creates a detached thread followed by a joinable
|
|
thread to exercise different code paths. A barrier is used to ensure
|
|
the detached thread has started before the joinable one is created,
|
|
making the test more deterministic. The tst-dl-debug-tid.sh shell script
|
|
wrapper then verifies the LD_DEBUG output. */
