* Test that assertions and messages are thread-safe.
|
|
*
|
|
* This is done by spamming assertions and messages on multiple subthreads.
|
|
* In manual, this reliably causes segfaults if the test is linked against
|
|
* a non-thread-safe version of Catch2.
|
|
*
|
|
* The CTest test definition should also verify that the final assertion
|
|
* count is correct.
