            Bug ID: 22368
           Summary: LLVMParseBitcode and LLVMParseBitcodeInContext exit on
                    error
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

LLVMParseBitcode() and LLVMParseBitcodeInContext() are specified to return true
on error, false if ok; they also put the error message in the given
pointer-to-string.

However, with 3.6rc1, those functions now exit(1) on error. This is because of
LLVMContext::diagnose(). From C code there is therefore no obvious way to get
back an error properly.
