[Bug java/32853] New: [4.3 regression] failing libjava testcases

seen with 20070720 trunk; the failing testcases use all available RAM, then
fail. (note: seen with the libjava backport for 4.1 as well)

glibc 2.6 related? unreproducible with a glibc downgraded to 2.5

this is not a bug in gij, but in glibc (2.6?), apparently fixed by:

2006-11-30  Jan Kratochvil  <jan.kratochvil@redhat.com>

        * sysdeps/unix/sysv/linux/x86_64/clone.S: Provide CFI for the outermost
        `clone' function to ensure proper unwinding stop of gdb.

and

2006-11-30  Jan Kratochvil  <jan.kratochvil@redhat.com>

        * sysdeps/unix/sysv/linux/i386/clone.S: Provide CFI for the outermost
        `clone' function to ensure proper unwinding stop of gdb.

found in the glibc FC branch, but not in HEAD and glibc-2_6-branch.

I don't get it.  The changelog entry is for _adding_ the directives
and matches the changelog entry in glibc HEAD.  This patch removes
them.

If removing them makes anything better then it's got to be a bug in
java's unwinder.

Java just uses the unwinder in libgcc_s.  The same one that C++ and C use.  If
it is a problem with the unwinder one might expect to see it in those languages
as well.

However, it would seem to be somewhat system dependent:

One should read:
http://sourceware.org/ml/gdb/2006-12/msg00100.html
And:
http://sourceware.org/ml/gdb-patches/2006-12/msg00178.html


I don't know if this counts as a GCC bug or a glibc one now.

The glibc patch now is included in glibc-2.6.1, the failing test cases are not
known anymore. Closing the report.
