[Bug libgcj/35552] New: GCJ ARM compiled programs give segmentation fault

["zkhan at d2tech dot com" <gcc-bugzilla@gcc.gnu.org>]

I am trying to run GCJ on ARM9 platform from Texas Instruments / Monta Vista
(MVLCEE3.3.1 OMAP730).

Problem: GCJ builds fine, but when I run programs compiled by it, it gives me
segmentation fault.

This is my target system:
ARM9TDMI
MV Linux 2.4.20
Glibc 2.3.2
Binutils 2.14
GCC 3.3.1


So I cross compiled for this system using crosstool with following parameters:
ARM9TDMI
Linux Headers 2.4.20
Glibc 2.3.2
Binutils 2.14
GCC core 3.4.0
GCC (langs=c,c++,java) 4.2.3

1. arm-9tdmi-linux-gnu-gcc HelloWorld.c -o Hello-c -> Works fine on target
system
2. arm-9tdmi-linux-gnu-c++ HelloWorld.cpp -o Hello-cpp -> Works fine on target
system
3. arm-9tdmi-linux-gnu-gcj HelloWorld.java --main=HelloWorld -o Hello-java ->
Segmentation fault on target (same with -static)


Then I tried another combination of tools to try on QEMU ARM emulator which is
running
ARM9TDMI
Linux 2.6.18
Glibc 2.3.6
Binutils unknown
GCC 4.1.1

Using crosstools made a second set of toolchain
ARM9TDMI
Linux headers 2.6.18
Glibc 2.3.2 (2.3.6 does not build with this combination)
GCC core 3.4.0
Binutils 2.16.1
GCC (langs=c,c++,java) 4.2.3

I have same segmentation fault issue on emulator. I have tried with TLS or
without TLS support, same problem.

Does GCJ work in release 4.2.3?


Some config info from crosstool:
