> How hard is it to write a testcase that triggers the problem?

I wrote one and I thought I posted it here. But I had forgotten
to attach the patch! (git reflog just saved my life).

Here it is again.

gdb/testsuite/ChangeLog:

        * gdb.dwarf2/dw2-icycle.S, gdb.dwarf2/dw2-icycle.c,
        gdb.dwarf2/dw2-icycle.exp: New files.

This testcase fails without the patch being proposed.

Thanks,
