-> Including the preprocessed File doesn't make sense, since

-> I made a test case

Comment 1 Christoph Schmalhofer 2005-10-11 11:20:01 UTC

Created attachment 53616 [details]
testcase for Bug #124230

untar and see header/README

Comment 2 Christoph Schmalhofer 2005-10-24 13:53:16 UTC

Null pointer passed to memcmp libcpp/files.c line 672 :

	  same_file_p = read_file (pfile, ref_file)
			/* Size might have changed in read_file().  */
			&& ref_file->st.st_size == file->st.st_size
!sometimes null!	            && !memcmp (ref_file->buffer,
				    file->buffer,
				    file->st.st_size);


This works for me:
christoph@linux:/usr/src/packages/BUILD> diff gcc-4.0.2-20050901/libcpp/files.c gcc-4.0.2-20050901/libcpp/files.c.original
672c672
<         same_file_p = ref_file->buffer && read_file (pfile, ref_file)
---
>         same_file_p = read_file (pfile, ref_file)

Comment 3 Michael Matz 2007-01-24 14:05:49 UTC

Fixed meanwhile on gcc 4.1.x .
