That value looks like text: "01 71\n\n\n", so the heap appears to be
corrupt. If you have a core file then looking at other memory nearby,
things like pool->tag and pool->self, might help.
The pool pointer 0x7fbc49587028 is r->pool passed all the way through
from here:
#15 0x00007fbc4d390538 in svn_repos_has_capability (repos=0x7fbc4958d490,
has=has@entry=0x7fff6437f290, capability=<optimized out>,

That is early in Subversion's handling of the request. Subversion might
be responsible for the corruption, but it is also possible that some
other Apache module was responsible.
