I get a reduced test case for this bug. Attached here.
segv fault is cause by following code snip in cp/mangle.c
static tree
mangle_decl_string (const tree decl)
{
...
input_location = DECL_SOURCE_LOCATION (decl); // input_location is ZERO
...
write_mangled_name (decl, true); // Segv

This bug was reported upstreams, and has been fixed in gcc 4.6.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44787
This bug might be introduced to linaro gcc 4.5 when we backport patches
from gcc 4.6. Backport patch to in my local linaro 4.5 tree, and see
ICE goes away.

I can reproduce it on imx51, but can't reproduce it on other two boards. Both
openjdk and eglibc are the same on these three boards,
openjdk-6-jre-headless: 6b18-1.8-2ubuntu2
eglibc:2.12.1-0ubuntu3
Run 'java -version', and here is the result,
imx51-1
Matthias,
I am building latest eglibc on pavo1, which may take some hours. If you have
some arm boxes at hand, and see seg fault on it, I'd like to log in to have a
look.

Can't reproduce this problem, here are steps,
1 Remove cvs-revert-flush-cache-textrels.diff from patch/series.
2 Rebuild eglibc
3 dpkg -i libc6_2.12.1-0ubuntu1_armel.deb
4 cp /usr/lib/jvm/java-6-openjdk/jre/lib/arm/server/libjvm.so .
5 Run ./testcase, no seg fault.
6. strace -o 3.log java

that eglibc (2.12.1-0ubuntu1) is based on eglibc svn r11211, while
eglibc (2.12-0ubuntu4) is based on eglibc svn r10817. Run diff between
r10817 and r11211, don't see something special may fix this bug.

Get ICE on maverick/x86 also. Cross compile linaro gcc *without*
patches, ICE goes away.
After compare 4.4.4-7ubuntu3 and linaro gcc, one difference is that
-fstack-protector is put in 4.4.4-7ubuntu3 gcc's spec.
Remove gcc-default-ssp.diff from rules.patch, and rebuild gcc on x86.
No ICE any
Checkout firefox code from mozilla.org, configured, and built. Still segfaults.
Here is a list of steps I did,
1. hg clone http://hg.mozilla.org/releases/mozilla-1.9.2/ 192src
2. cd 192src/js/src
3. ~/autoconf-2.13-install/bin/autoconf
4. ./configure
5. make
./dist/bin/js imacro_asm.js
Configured and built firefox on pavo1 with different options,
./configure --disable-optimize --enable-debug
CFLAGS=-g -ggdb -O0 -fno-strict-aliasing -Wall CXXFLAGS=$CFLAGS make
MODULE_OPTIMIZE_FLAGS= INTERP_OPTIMIZER= MOZ_OPTIMIZE_FLAGS=
No segfault.
./configure --enable-debug
CFLAGS=-g -ggdb
./configure --enable-debug
make
No segfault. Attached generated imacros.c.tmp
However,
./configure
Add -fno-inline -fno-strict-aliasing in INTERP_OPTIMIZER,
MODULE_OPTIMIZE_FLAGS, and MOZ_OPTIMIZE_FLAGS. Segfaults.
** Attachment added: imacros.c.tmp
ICE is still there on gcc 4.4.4-7ubuntu1~ppa2,
