[Bug c++/27052] New: When using excessive -ftemplate-depth g++ segfaults

[gcc at magfr dot user dot lysator dot liu dot se]

When compiling foo.C using the command line g++ -ftemplate-depth-20000 foo.C

the result is

g++: Internal error: Segmentation fault (program cc1plus)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

instead of the expected
foo.C:3: error: template instantiation depth exceeds maximum of 20000 (use
-ftemplate-depth-NN to increase the maximum) instantiating 'struct foo<20000u>'
foo.C:3:   instantiated from 'foo<19999u>'
...
foo.C:3:   instantiated from 'foo<0u>'
foo.C:8:   instantiated from here

foo.C:3: error: incomplete type 'foo<20000u>' used in nested name specifier
