--- Comment #4 from nik <xerofoify at gmail dot com> ---
I have new to the project but after looking at the code in semantics.c that was
changed by that commit pointed out. It seems that a else above this if
statement was removed:

if (containing_function && DECL_TEMPLATE_INFO (context)
    && LAMBDA_FUNCTION_P (containing_function))

which in term means that:
containing_function = NULL_TREE;

is a NULL_TREE I assume that means it points to a nullptr or null pointer.
Therefore we may be passing in a null tree to an incorrect branch due to the
missing else. Seems it your trace, semantics.c is being called so it may be
this. Anybody have any comments?
