--- Comment #32 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Using: RUN_UNDER_VALGRIND= \ make check-jit \ RUNTESTFLAGS="-v -v -v jit.exp=test-factorial.c" trunk currently shows this: LEAK SUMMARY: definitely lost: 55,908 bytes in 654 blocks indirectly lost: 107,842 bytes in 1,630 blocks possibly lost: 0 bytes in 0 blocks still reachable: 2,075,133 bytes in 686 blocks suppressed: 0 bytes in 0 blocks so there are still some memory leaks.
