While running "make test", my system became very sluggish because one of the tetss for yaml seems to contain a memleak (on my system, the process was finally killed after the test grew to 1.8GB RSS). The output is:
t/00basic.....ok
t/01pass......ok
t/02fail......ok
t/10dump......ok
t/11code......ok
t/12nest......ok
t/13opts......ok
t/20load......dubious
Test returned status 0 (wstat 11, 0xb)
DIED. FAILED tests 3-17
Failed 15/17 tests, 11.76% okay
t/21spec......ok
t/22slides....ok
t/30errors....ok
t/test1.......ok
The test itself doesn't output anything interesting, it just grows and eventually gets killed by the kernel.
