i've noticed that my ss20 can't run the regress/lib/libpthread/find
test without lowering my stack size.
this test gets the current stacksize and allocates it approximately
350 times:
#define NUM 100
for (i = 0; i< NUM; i++) {
...
malloc((random()& 7) * sl.rlim_cur);
}
by default for me, it fails on the last iteration. if i lower
my stacksize limit from 8MB to 6MB it does not fail. if i raise
my stackszie limit to the maximum, it fails after 23 iterations.
i can't get the t_lwpctl test to fail though.
It's a strange bug. When this bug occurs, it is reproductible until I
reboot my SS20. I think there is a kernel stack corruption somewhere in
kernel but I can not invetigate. My SS20 is not stable enough :-(
