APAR status
Closed as program error.
Error description
When the 'label value expressions' IBM extension is used incorrectly (i.e. referencing a label OUTSIDE the current function), the compiler encounters an internal compiler error instead of outputting an informative error message. === TEST CASE === static void* ext[1] = { &&sym }; void test() { int check = 0; switch (check) { sym: default: {} break; } } $ xlc -c test.c xlc: 1501-230 (S) Internal compiler error; please contact your Service Representative.

Local fix
Correct invalid label usage.
Problem summary
PROBLEM DESCRIPTION: Compilation failed with an internal compiler error. USERS AFFECTED: Users attempting to use the 'label value expression' extension incorrectly (outside of a function scope).
Problem conclusion
The compiler now issues an error diagnostic instead of failing with an internal compiler error when compiling label value expressions that appear outside function scope.
