Hi Nicolas.

1/ Have now checked in config.log for -g flag with --enable-debug.
It's OK. Also other checks on compiler options - all OK. I hadn't checked enough
when I reported possible problem - apologies.

2/ Now I've got the hang of the compiler options, stacktrace has more
information.
Compiled with:
../configure \
--with-boost-src=/tmp/boost_1_34_1 \
--disable-optimiz \
--disable-optimiz-arch \
--enable-debug \
COMPILED_BY="Option 5"
