This is a compiler-internal error with using the -g option.

It means that the (file, line) location number has line == 0 and the
compiler refuses to emit DWARF info with line == 0 because (according
to the comment in the source) clang fails to process such files.

Because camlp5 is a preprocessor it's probably generating fake line
number info.

Up to you how far you want to diagnose and/or fix this.  TBH I
wouldn't bother trying too hard to fix this.  Just don't use -g on the
affected files if possible, or turn off debuginfo on the whole
