You have a pool cleanup bug in the --parallel C tests mode. After these
last two commits:

$ make check PARALLEL=1
...
At least one test FAILED, checking /Volumes/build-trunk-amalgamated/tests.log

Here's the example of what tests.log has to say about these failures:

changes-test(16390,0x7fff7d921180) malloc: *** error for object 0x7fc251011800: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

And this is what the debugger says:

$ glibtool --mode=execute lldb -- subversion/tests/libsvn_clit-test --parallel
Current executable set to 'subversion/tests/libsvn_client/.libs/client-test' (x86_64).
