offset and len in the first line correspond to offset 0x100000000
and len 0xffffe000 resp.  So I do not see the values you printed from GDB
below.

This is general debugging of GDB, it no longer belongs to this list.
You should best file it to GDB Bugzilla and try to provide reproducibility
information.


There seems to be some 32->64bit extension problem (0x100000000).  Isn't the
GDB built for x86_64 target while you run it for i386 target?  This sure
should work but there may be some issues.  Try to build 32-bit host GDB as
troubleshooting:
	CFLAGS=-m32 ./configure i386-unknown-linux-gnu
But this is already rather for the Bugzilla.
