[Bug bootstrap/44655] New: bootstrap failure, stage1 xgcc miscompiles gengtype-lex.l gengtype SEGVs

["bugzilla-gcc at thewrittenword dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Building released gcc-4.4.4 on ia64-hp-hpux11.23 and 11.31 fails:
echo timestamp > s-gtyp-input
build/gengtype /opt/build/gcc-4.4.4/gcc gtyp-input.list
gmake[3]: *** [s-gtype] Segmentation fault (core dumped)

Program terminated with signal 11, Segmentation fault.

#0  0x401dd80:0 in yylex (yylval=0x40011a0c) at gengtype-lex.l:193
193     gengtype-lex.l: No such file or directory.
        in gengtype-lex.l

Rebuilding gengtype-lex.o and gengtype with -O2 -fno-schedule-insns works.

The build was bootstrapped with gcc-4.2.4.
