http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51318 --- Comment #6 from Paolo Carlini paolo.carlini at oracle dot com 2011-12-04 16:32:52 UTC --- For some reason, in mainline tsubst_template_arg (thus tsubst_expr - tsubst_copy_and_build, which crashes because TREE_TYPE (r) is null) handles an INDIRECT_REF (with a COND_EXPR as arg 0) instead of a COND_EXPR.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51318 --- Comment #3 from Marc Glisse marc.glisse at normalesup dot org 2011-12-01 21:42:35 UTC --- (In reply to comment #2) Marc, do you have a feeling PR51384 is a duplicate? At least I produced this testcase starting from the one-liner: #include Eigen/Dense that made g++ segfault and applying delta. So yes, I'd say it's a dup (although there could in principle be several g++ bugs and delta would highlight one that may not be the one giving the backtrace in PR51384).

Confirmed. Even simpler testcase:

enum { e0, e1 };
templatebool B, int = B ? e0 : e1 struct A {};
templatetypename T struct B
{
AT::X a;
};
=
