Hello,

Unfortunatelly I do not have resources right now to check it :(
However, the failure was encountered on very common platform
i686-pc-linux-gnu, so it would be nice if someone could spare some
CPU time to do bootstrap with
BOOT_CFLAGS="-O -fomit-frame-pointer -fno-defer-pop -fno-thread-jumps"
(Those -fno-... options are not required to reproduce debugging, IIRC.
They were added just to narrow the set of active optimizations, I
think) I'll check myself as soon as I am able to. (In a month or
two...)
