Subject: lam: FTBFS on m68k due to ICE, try lower optimization?

Package: lam
Severity: serious
Justification: Policy 4.2

lam currently fails to build on m68k due to an internal gcc error:

ndi_parse.c: In function 'ndi_parse1':
ndi_parse.c:241: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-4.0/README.Bugs>.

This needs to be fixed in gcc, but in the meantime it's holding up the
lam transition into testing, which in turn is holding up hdf5 and
mpich. Perhaps you could try lowering the optimization to -O2 on
m68k to see if that works around this problem?

I took a quick look and didn't see the obvious way to make this change,
but if you need help finding a clean way to make this happen, please
let me know and I'll take a closer look.

Package: lam
Followup-For: Bug #328206

Here is a patch to lower the optimization level of lam from -O3 to -O2.
This will hopefully resolve the m68k build problem, and debian-devel
mail seems to indicate this is a good idea for i386 as well.

I've tested this patch and confirmed that lam still builds and that
this eliminates any use of -O3.
