libcpp/charset.c preprocessor output

While bootstrapping gcc-4.8.5 with solution from PR 64919 - (bootstrap failure
of gcc-4.9.2 on ia64-hpux in libgcc)
encountered one fault:
while compiling libcpp/charset.c on stage2 & stage3 xg++ was ICE. (see detail
in attachments)

I was change (on stage 2&3) command line from -O2 to -O1 optimization option
and everithing was fine. The gcc now bootstrapped and used.
