When trying to build gcc trunk lately (last month maybe), I get a
problem with building libjava. It's like this:

/bin/sh ./libtool --tag=GCJ --mode=link /usr/local/src/trunk/objdir32/gcc/gcj -B/usr/local/src/trunk/objdir32/gcc/ -B/usr/local/sparc-linux/bin/ -B/usr/local/sparc-linux/lib/ -isystem /usr/local/sparc-linux/include -isystem /usr/local/sparc-linux/sys-include -L/usr/local/src/trunk/objdir32/sparc-linux/libjava -g -O2  -o libgcj0_convenience.la   prims.lo <stuff deleted>

Now, debugging this, using gdb-6.3.0.0-0.29 (from rawhide), I see this:

Any ideas of what might go wrong? Can I provide more information to

perhaps finding a way ahead?

hmm, I think I will have to bail out of this now, debugging seems to
take "forever" and it might even be the case that it does not give me
anything.

Speculating about the resons for this problem, I would say it's either
my developmnet system and its development kernel that does memory
trashing in a way that affercs binutils ar like this, or it is a gcc
miscompilation (which seems to me far off but still possible) or it is
a binutils "bug".

For anyone interested in digging into this, I have put a tarred
achhive of the .o files togheter that you can run your favourite ar
capable of reading sparc-linux .o files and producing sparc-linux
archives together with a text file that describes my setup, the
verisons used, my test run of ar and a simple gdb back trace of the
Bus error I get.

It's available, for some time..., at 

ftp://ftp.j-son.org/pub/aurora/ar-problem-corona/

after all, maybe this is a kernel memory trashing issue, if I run ar
with kernel-2.6.9-1.1032sp1 the thing does not happen, but when I run
with kernel-2.6.10-1.1110sparc18 it does. I will try with
kernel-2.6.11-1.1166sp1 later today...

give up now...
