           Summary: crash on unclosed asm
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW

reduced test case (provided by Craig Schroeder)

clang trunk crashes on this input after issuing the error (when in C mode):

int vscanf () __asm__ (("")

the result is:

t15.c:1:24: error: expected string literal
int vscanf () __asm__ (("")

(and then it crashes in Parser::ParseSimpleAsm).
