First off, please submit a bug report to http://gcc.gnu.org/bugs.html
as the compiler error requests.  It's important to include preprocessed
source.  To get that, give the same gcc command as before, but with -E
instead of -c.  To be precise, the following commands should do it:

cd /home/nags/toolchain/toolchain-libs/build/xc/programs/xterm

/opt/EncorePxa-tools/bin/gcc \
-I. -I../../exports/include \
-I../../exports/include -I../../exports/include/freetype2  \
-I../../exports/include/X11  -I../.. -I../../exports/include -Dlinux \
-D__arm__ -D__arm32__ -U__arm -Uarm \
-D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE \
-D_XOPEN_SOURCE -D_BSD_SOURCE \
-D_SVID_SOURCE  -D_GNU_SOURCE \
-DFUNCPROTO=15 -DNARROWPROTO  -DSCROLLBAR_RIGHT -DOPT_WIDE_CHARS \
-DOPT_LUIT_PROG -DXRENDERFONT -DXFREE86_FT2 \
-DPROJECTROOT=/usr/X11R6  -E -o ~/fontutils.i fontutils.c

Then verify that the .i file reproduces the crash with the command

/opt/EncorePxa-tools/bin/gcc -O3 -fno-strict-aliasing -fsigned-char ~/fontutils.i

If it does, great, you've bottled the problem up for analysis!
Compress it with
   gzip fontutils.i
and attach the file fontutils.i.gz to the bug report.

Once you've done that, I can help you further.
