The bug is that the compiler should be reporting a
"assignment of read-only location" at line 5 of test.cc (provided below)
whenever '-fwritable-strings' (or something that invokes it) is not
present.  I have tried explicitly using '-fno-writable-strings' to
no effect.

Line 5 of test.cc is the line that reads:  
  "abcd"[2] = 'x'; 

I believe the problem is that the compiler is treating string literals
as being of type (char *) regardless of command-line options.

Machine name and compiler output are in gcc.runtime.info .

Test program is in test.cc .

Compiler preprocessor output is in test.out.cc .

Configuration file for compiler make ( config.status ) is in config.status.

No changes were made to the compiler.

Compiler was installed by "make -install".
