Files generated by the good and bad revision

Seems that LLVM is missing some assembly parts for generating code for the
attached files and the following error is generated:

/tmp/version-c0461b.s: Assembler messages:
/tmp/version-c0461b.s:93: Error: junk at end of line, first unrecognized
character is `"'
/tmp/version-c0461b.s:649: Error: bad expression
/tmp/version-c0461b.s:649: Error: junk at end of line, first unrecognized
character is `.'

The assembly generated for the same file gives:

 88         .section        __ksymtab_strings,"a",%progbits                     
 89 .L__ksymtab_strings_end:                                                    
 90         .data                                                               
 91 .L.data_end:                                                                
 92         .section        .rodata,"a",%progbits

 94         .section        .debug_info,"",%progbits                            
 95 .L.debug_info_begin0:                                                       
 96         .long   564                                                         
 97         .short  4                                                           
 98         .long   .L.debug_abbrev_begin    

Find also attached two folders containing the GOOD (r191049) and the BAD
(r191065) files.
