+Debugging with gdb and strace
+=============================
 
 The new test library runs the actual test, i.e. the `test()` function in a
 forked process. To get stack trace of a crashing test in gdb it's needed to
 [`set follow-fork-mode child`](https://ftp.gnu.org/old-gnu/Manuals/gdb/html_node/gdb_25.html).
+To trace test with strace use `-f`.
