--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> 2012-12-07 12:01:45 UTC ---
 fooisl_ctx.c:158: isl_ctx freed, but some objects still reference it

this probably means some other data structure leaks:

==6257== 23,443 (48 direct, 23,395 indirect) bytes in 1 blocks are definitely

and some more.  I have a patch for the testcases at least.
