The following test case gives an internal compiler error when compiled for
alpha-linux:
$ cat pad2.i
extern char letters[26+1];
char letter;
int letter_number;
char letters[] = "AbCdefghiJklmNopQrStuVwXyZ";
static void
pad_home1 ()
{
letter = letters[letter_number =
letters[letter_number + 1] ? letter_number +
1 : 0];
}
$ gcc -v -S pad2.i

Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/faq.html#bugreport> for instructions.
Please note that the abort does not occur when the first line (extern
declaration for letters) is deleted. The problem is that the compiler
generates a MEM rtx for the variable letters without a mode:
(mem/s (symbol_ref:DI ("letters")) 0)
