The first lambda produces a warning. It compiles but the program behaves wrong.
The second lambda crashes the compiler.

Compiling with: "g++-4.7.2 -std=c++11 -Wall -Wextra"

The first lambda produces the following warnign:
"warning: missing initializer for member ‘B<D>::foo() [with D =
void]::lambda()>::__this’ [-Wmissing-field-initializers]"

It recognizes that it has to capture the this pointer, but it does not
initialize it. The code compiles and the executable does not print 10 as it
should.

The second lambda crashes gcc with the following error:
"internal compiler error: in get_expr_operands, at tree-ssa-operands.c:1035"
