Hi,
Please find below some problem related to mallocstress testcase failing
on x86_64. Let us know if some of you have encountered this.

I was able to recreate the problem by spawning only 2 threads:
This is what I found:
------------------------------------------------------------------------------------
[pid 8006] tgkill(8004, 8006, SIGABRT <unfinished ...>
[pid 8005] <... mmap resumed> ) = 0x7f8ba781b000
[pid 8006] <... tgkill resumed> ) = 0
[pid 8005] nanosleep({0, 0}, <unfinished ...>

Process 8006 detached
[pid 8005] <... nanosleep resumed> NULL) = 0
[pid 8005] +++ killed by SIGABRT +++
+++ killed by SIGABRT +++
------------------------------------------------------------------------------------
So one of the thread is sending tgkill to whole group. Need to look into glibc
code to understand the problem. Test case is failing strangely while calling
free()
=================================
for (i = 0; i < num_alloc; i++)
{
dprt(("pid[%d]: freeing ptrs[i] %p\n", getpid(), ptrs[i]));
if (ptrs[i][0] != i) {
fprintf(stderr, "pid[%d]: fail: bad sentinel value\n", getpid());
return 1;
}
free(ptrs[i]); <== Problem area
my_yield();
}
=================================
