Hi Padraig,

make check passes here on openSUSE-13.1, but check-expensive fails
for 'tests/misc/shuf-reservoir.sh':

  + return 1
  + fail=1
  + echo 'shuf-reservoir-sampling failed with IN_N=0 OUT_N=0'
  shuf-reservoir-sampling failed with IN_N=0 OUT_N=0

This is obviously a false-positive as the code freeing memory is
"#ifdef lint"-ed in src/shuf.c ... although it should use IF_LINT(...).

I'm wondering why the other valgrind'ed tests could work.

Have a nice day,
Berny
