            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

  Target Milestone: ---

Created attachment 51443
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51443&action=edit
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 forgot to mention that the same code compiles successfully with gcc 9.4.0.

And here is the output from gcc 11.1.0:

The code compiles if -std=c++03 is replaced with e.g. -std=c++11.

This bug isn't about a warning but about an ICE. Are you positive this is a
duplicate?
