I’ve been hunting an intermittent jdk crash on sparc64 for some time now.
Since egdb has not been up to the task, I created a small c program which
reproduces the problem. This partially mimics the jdk startup where a number
of detached threads are created. When each thread is created the main thread
waits for it to start and change state. In my test program I then have the
detached thread wait for a condition that will not happen (parked waiting
on a condition var).
When the intermittent crash occurs, one of two things happen; a segfault or
the process has been killed by the kernel. The segfault cores are similar to
what I see with the jdk crashes. It looks like the stack of the thread creating
the threads is corrupted. In this case it is the primordial thread. In the jdk
it is a different thread but its the thread that called pthread_create that
has it stack wiped out.
The problem is sparc64 specific. The jdk doesn’t crash like this on arm64,
amd64 or i386 and the test program has run for over 1 million iterations on
each of those platforms without an issue.

This counts the number of iterations until the test program fails and
restarts the count.
