[Bug c++/30851] New: [4.1/4.2/4.3 regression] ICE with invalid asm statement

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 3.4.0:

=====================================
void foo()
{
  asm ("%[x]" : [0](x));
}
=====================================

bug.cc: In function 'void foo()':
bug.cc:3: error: expected identifier before numeric constant
bug.cc:3: error: expected `]' before numeric constant
bug.cc:3: error: expected string-literal before numeric constant
bug.cc:3: error: expected `(' before numeric constant
bug.cc:3: error: expected `)' before ']' token
bug.cc:3: error: expected `)' before ']' token
bug.cc:3: internal compiler error: tree check: expected string_cst, have
error_mark in resolve_operand_name_1, at stmt.c:1320
Please submit a full bug report, [etc.]

The bug is similar to PR 30849 and PR 30850, but the crash is in a different
function.
