PR c++/20020 concerns a crash in cp_print_value_fields. The immediate cause is that cp_print_value_fields does not handle the case where value_static_field fails. This is fixed in this patch by calling cp_print_static_field from the "try" block. Digging a bit deeper, the error occurs because GCC does not emit a DW_AT_const_value for a static constexpr member appearing in a template class. I've filed a GCC bug for this. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-05-29 Tom Tromey <tromey@adacore.com> PR c++/20020: * cp-valprint.c (cp_print_value_fields): Call cp_print_static_field inside "try". gdb/testsuite/ChangeLog 2019-05-29 Tom Tromey <tromey@adacore.com> PR c++/20020: * gdb.cp/constexpr-field.exp: New file. * gdb.cp/constexpr-field.cc: New file.
