Bug ID: 102293
Summary: [10 regression] ICE when compiling Boost.Xpressive (in
value_dependent_expression_p, at cp/pt.c:26730)
Product: gcc
Version: 10.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: andysem at mail dot ru
Target Milestone: ---

Preprocessed output of the failing test.
I'm seeing ICE with gcc 10.3.0 and gcc 11.1.0 when compiling Boost.Log tests
that use Boost.Xpressive. The ICE points at Boost.Xpressive code:

I'm attaching the preprocessed output of the test.
For reference, this happens with Boost 1.77.0, as well as the current develop
branch (boost superproject revision 091e69b53b55274ff81629a8e3f64ca782ca7722).
