Bug ID: 96741
Summary: ICE in value_dependent_expression_p when compiling
Boost.Xpressive in C++03 mode
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: andysem at mail dot ru
Target Milestone: ---
Created attachment 49097

Preprocessed source of the test that fails to compile with ICE
Attached is the preprocessed source of a Boost.Log test that uses
Boost.Xpressive, which fails to compile with ICE in C++03 mode. The same code
compiles in C++11 mode. Also compiles with gcc 9.3, both in C++03 and C++11.
