libgcj problems on panther

[Andreas Tobler <toa at pop dot agri dot ch>]

Hi all,

since a few days panther (OS-X 10.3) is out and gives us some nice 
improvements regarding build speed. Unfortunately we also have a serious 
 problem to run the testsuite in libgcj. It is not only testsuite related.

See here: http://gcc.gnu.org/ml/gcc-testresults/2003-11/msg00367.html 
for a sample of the results.

If we run a test by hand it will succeed if we do it right:)
But it should not be necessary to pay attention to some settings. It 
should always run.

Lets take the ArrayStore.exe

If we run it in the testsuite directory we succeed:
titanium:powerpc-apple-darwin7.0.0/libjava/testsuite] andreast% 
./ArrayStore.exe
java.lang.ArrayStoreException
java.lang.ArrayStoreException
java.lang.ArrayIndexOutOfBoundsException
foobar

We change to the builddir:

[titanium:objdir/powerpc-apple-darwin7.0.0/libjava] andreast% 
./testsuite/ArrayStore.exe
Bus error

This is with CLASSPATH not set.

If we set the CLASSPATH var the app always Bus Errors.

Below you find a bt full of such a crash.

The same happens for 'gij ArrayStore'

Andrew Pinski found out, if we remove the 
gnu/gcj/convert/Output_ASCII.class from the buildtree, the app runs with 
and with out CLASSPATH set. It also runs in the builddir.

In darwin6.3 everything went fine. One improvement from darwin6.3 to 
darwin7.0 is wchar support. Maybe this is related ?

For the moment I'm stuck with analyzing, do you have an idea on how to 
debug?

Thanks for any pointer.

Andreas
