c++: ICE with erroneous template redeclaration [PR106311]
Here we ICE trying to get DECL_SOURCE_LOCATION of the parm that happens
to be error_mark_node in this ill-formed test. I kept running into this
while reducing code, so it'd be good to have it fixed.
PR c++/106311
gcc/cp/ChangeLog:
* pt.cc (redeclare_class_template): Check DECL_P before accessing
DECL_SOURCE_LOCATION.
gcc/testsuite/ChangeLog:
* g++.dg/template/redecl5.C: New test.
