When compiling the source *ackermann.cpp* for the attached file *ackermann.ii*
with
g++ -Wall -std=c++0x -ftemplate-depth=100000 -save-temps ackermann.cpp

I get the following error:
g++: internal compiler error: Segmentation fault (program cc1plus)

You are most likely hitting the stack limit.

And indeed, I can confirm that the problem is the stack. Likewise happens with
clang++.

Yes, I also submitted the bug (15551) to clang. Doesn't seem to kill intel's
icc though.

ICC Produces:
<source>(3): internal error: bad pointer
    static unsigned long long const result =
Ackermann<(m-1),Ackermann<m,(n-1)>::result>::result;
                                                                          ^


There is not much to fix here. The limit is there to give a reasonable limit so
you don't run into problems like this.
