Thank you for reporting that.
At first glance, that failing assertion seems due to a bug in your
system's version of valgrind.  I don't immediately see a clean way
to work around it.  Sure, the dirty way would be to search for this
line:

> valgrind: m_debuginfo/readdwarf.c:2329 (copy_convert_CfiExpr_tree): Assertion 'srcix >= 0 && srcix < VG_(sizeXA)(srcxa)' failed.

and when found, skip the test, saying "your version of valgrind is
inadequate".  In any case, this failure does not mean sort has a
problem.  Just valgrind, and maybe the test itself, for relying
on valgrind.
