The following invalid code snippet triggers an ICE since GCC 3.4.0:
=====================================
void foo()
{
asm("" :: 0);
}
=====================================
bug.cc: In function 'void foo()':
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: internal compiler error: tree check: expected string_cst, have
error_mark in resolve_asm_operand_names, at stmt.c:1234
Please submit a full bug report, [etc.]
The bug is similar to PR 30849, but the crash is in a different function.
