I think I was a little hasty here. Some of the assertions that occur before the tests start do involve Subversion code.

However these do look important: ==13541== Conditional jump or move depends on uninitialised value(s) ==13541== at 0x7211D2C: svn_md5__digest_to_cstring (md5.c:62) ==13541== by 0x7211E02:

One other thing that worries me is the runtime for the tests. On compiled code, such as libsvn_subr/path-tests, running under valgrind is usually 10 to 100 times slower but the ruby tests are only a little bit slower, less than a factor of 2. I'm not sure why there is such a difference between compiled C code and byte-compiled ruby code? Perhaps valgrind does some sort of byte-compiling? Or perhaps it's to do with how long the ruby tests take on my machine compared to Hyrum's machine (528 seconds versus 18 seconds). -- Philip
