PR modula2/115003 exporting a symbol to outer scope with a name clash causes ICE
An ICE will occur if an unknown symbol is exported and causes a name
clash. The error mechanism attempts to find the scope of an unknown
symbol. This patch adds a missing case clause to GetScope and returns
NulSym if the scope is an unknown symbol.
gcc/m2/ChangeLog:
PR modula2/115003
* gm2-compiler/SymbolTable.mod (GetScope): Add UndefinedSym
case clause and return NulSym.
