[Bug c++/42355] New: Segmentation fault

I don't think I can provide the source code.
But maybe the debug output already provides some hints.
This is using boost 1_39

the compiler takes more than 10GB of RAM.
There is 40GB of RAM available.

Please update to 4.4.2 at least.  Without a testcase we can't do anything
here.

------- Comment #10 from rguenth at gcc dot gnu dot org  2010-01-04 19:39 -------
Please also provide output of g++ -v.  If you manage to compile this
successfully then the output of -ftime-report will also be interesting.

Confirmed with -g (-g0 is very fast and lean).  G++ 4.1 doesn't want to
grok the testcase.

I guess these are _very_ long names (why again don't we output them
in mangled form?).  C++ component again.

boost::mpl::sort seems to be known to be a memory hog.
Also on other platforms.
I replaced this with other code.

Interesting clang is able to compile this reasonably but GCC and ICC have a
hard time.
