gij crashes in GC

I am not sure which component to report this bug against.
I did some investigations and I got to the boehm-gc.
I checked the latest CVS gcc4_0-branch and tried to "make check" in
boehm-gc directory. The test crashed too.

[Bug libgcj/20775] Crash in libgcj.so on linux alpha

[mckinlay at redhat dot com]

------- Additional Comments From mckinlay at redhat dot com  2005-04-05 21:46 -------
Is this is a Multi-processor machine? Does the crash always occur 100% in the
same place or is it intermittent? Thanks.

No, it is UP machine. Yes - it crashes at the same place all the time.

Then this is fixed for 3.4.4 and above by the following patch (which does the same):
2005-04-11  Richard Henderson  <rth@redhat.com>

        * include/private/gcconfig.h (alpha-linux): Use LINUX_STACKBOTTOM.
