Could it be different in 3.3? I try with 5 and no success but...

Yes the inlining is one factor:

The first works (see <http://lists.parisc-linux.org/pipermail/parisc-linux/2003-June/0
>0202.html>
;) and certainly the second too;

but also a better news:
(I definitely need to clean my glasses: in man default -finline-limit=600)

and it so works with -finline-limit= something between 350 (works) and 400
(failled). Now I am curio

-finline-limit (if i have some time)?

Sorry to reply to myself but I continue my test and reading again gcc man
(well all gcc-3.0, -3.2 and -3.3 are installed on this box and I would also
have to prefer to read man -l /usr/share/man/man1/gcc-3.3.1.gz).

And also re-reading <http://gcc.gnu.org/PR?10160> 

--param max-inline-insns=180 ... 5 # :( it fails
but otc
--param max-inline-insns-single=180 # ;) it works also (even if compile time
is
long versus -finline-limit=300) 

So looks like very much PR=10160 excepted that here it is not only a performance
pb but also a failure of compilation.


Thanks for you understand,
    Joel

ps: sorry also for bad quoting (pb with isp webmail)
