Subject: PR c++/88183 - ICE with .* fold-expression.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aaa6a4664b55ef69bd19c2dee94a40cb619f6330;p=gcc.git

PR c++/88183 - ICE with .* fold-expression.

build_m_component_ref can't handle type-dependent operands, so let's use the
default case; tsubst_copy_and_build also uses build_x_binary_op for
substituting a DOTSTAR_EXPR.

	* pt.c (fold_expression) [DOTSTAR_EXPR]: Remove special handling.
