gcc can place code into the .rodata section. I found this while debugging a
crash in Ingo Molnar's sched-devel kernel. In the kernel code

placed into the rodata. Later on in the kernel boot up sequence, the rodata

I think we are emitting the debug info too early for _testcom before we marked
it as a TLS.

After a clean bootstrap (empty build directory) I get a pass. I suspect we

I am discussing with Zdenek the proper fix.
Any conclusion in sight? If not, I'll xfail this as per protocol.

Well first it should be made HOST_WIDE_INT and x86 should move over to 64bit

When the exception thrown is an int instead of a class instance, everything
