Source file that demonstrates the probelm
Note: this issue exists in clang 3.5 as well but that was not an option.
1. Create a file called test.c with the following contents. Do not include the
spec required line ending at the end of the file. (Or use the attached file.)
int main()
{
#ifdef 1
#endif
return 0;
}
//With comment on last line of file clang will crash.
2. Run the following command to try to get the code completion options right
before the 1 in the file:
clang.exe -cc1 -fsyntax-only
-code-completion-at="C:\Users\xda\Desktop\test.c":3:8
"C:\Users\xda\Desktop\test.c"
3. Should get back no results but instead get an assert.
Assertion failed: BeginFileID == EndFileID, file
..\tools\clang\lib\AST\RawCommentList.cpp, line 108
4. Note, if you add the newline at the end of the file the issue goes away.</pre>
