Subject: [Caml-list] assert + -pp = wrong line number and filename in assert message
Date: 23 Aug 2001 12:28:16 -0400 [thread overview]
Message-ID: <yz1k7zu91wf.fsf@milhouse.cs.cornell.edu> (raw)
The "assert" construct generates an exception which contains the file
name and line number where the "assert" appears.
However, when a preprocessor is used (with the -pp option), the file name
and line number that are recorded are relative to the preprocessor
output file and not to original source file, even when the
'# linenum "filename"' directives are inserted in the preprocessor
output.
A quick scanner of ocaml-3.02/parsing/lexer.mll seems to indicate that
the line directive is completely ignored.
