gcj cross-compilation

[Nils Roeder]

Hi guys,

here is a stack trace from gdb.



$ arm-linux-gcj -v
Configured with: ../gcc-3.4.3/configure --target=arm-linux 
--prefix=/group/teaching/iar/armcore-gx/toolchain 
--enable-languages=c,c++,objc,java --disable-nls --nfp --with-cpu=xscale 
--with-softfloat-support=internal
Thread model: posix
gcc version 3.4.3

(btw. same for gcc version 4.0.1)

$ arm-linux-gcj -ggdb --main=HelloWorld -o hello HelloWorld.java
running ./hello causes segfault

$ gdb hello
Program received signal SIGSEGV, Segmentation fault.
