Hello He!
All,

The process to use an existing configuration is not to copy files, but to
tell crosstool-NG to use an existing sample:
ct-ng i686-nptl-linux-gnu

(Excerpt from your build.log:)
[ERROR] i686-nptl-linux-gnu-gcc: Internal error: Segmentation fault
(program as)
[ALL ] Please submit a full bug report.
[ALL ] See <http://gcc.gnu.org/bugs.html> for instructions.
As you can see by yourself, it's not crosstool-NG that fails, but 'as' that
is segfaulting.
It is difficult to remotely solve a segfault. There can be various causes
for a segfault. To try to debug this, ask yourself the following questions:
1) Does it happen again if you re-run the build?
- no: see (A), below
- yes: go to question 2
2) Does it happen systematically at the same point?
- no: see (A) below
- yes: go to question 3
3) Does it happen if you select other components for the toolchain?
- no, see (B), below
- yes, go to question 4
4) Does running other CPU/memory intensive applications (eg. video encoding
or other big compilation...) also segfault?
- no: see (A), below
- yes: see (B), below
(A) There is a non-reproducible glitch somewhere, most probably due to
any or many of:
- CPU/memory over-heating
- CPU/memory over-clocking
- one or more bad memory module(s)
This is known as the infamous "SIG11 problem", with explanations and
solutions described there: http://www.bitwizard.nl/sig11/
(B) Indeed, there is a problem when building this very source code.
In this case, try re-running the same compilation command manually
with debug turned on ( eg.: -v --verbose -Wa,-a=as-debug.log ) and
see what it says.
Sorry I can't help you more. Next time, please post to the crossgcc mailing
list, there are many nice and knowledgeable people hanging on there.
Regards,
Yann E. MORIN.

It *seems* to me that the answers in question 4 are swapped.
