From 9b0b45dc81e8f1bc5cf370f0a9a8f60b8d93f4e6 Mon Sep 17 00:00:00 2001 From: Richard Heck Date: Sun, 2 Apr 2017 20:59:23 -0400 Subject: [PATCH] Possible fix for bug #10295. As it was, the comparison buffer was sharing a DocumentClass with one of the compared buffers. I don't fully understand why this was causing a problem, since we use a shared_ptr. But this patch creates a new DocumentClass for the new buffer. --- src/Compare.cpp | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) diff --git a/src/Compare.cpp b/src/Compare.cpp index b2f64390f0..fee569907d 100644 --- a/src/Compare.cpp +++ b/src/Compare.cpp @@ -15,6 +15,8 @@ #include "Author.h" #include "BufferParams.h" #include "Changes.h" +#include "CutAndPaste.h" +#include "ErrorList.h" #include "Font.h" #include "insets/InsetText.h" @@ -382,7 +384,16 @@ void Compare::run() // Copy the buffer params to the destination buffer dest_buffer->params() = options_.settings_from_new ? new_buffer->params() : old_buffer->params(); - + + // We do not want to share the DocumentClass with the other Buffer + // See bug #10295 + DocumentClassConstPtr olddc = dest_buffer->params().documentClassPtr(); + dest_buffer->params().makeDocumentClass(); + ErrorList el; + cap::switchBetweenClasses( + olddc, dest_buffer->params().documentClassPtr(), + static_cast(dest_buffer->inset()), el); + // Copy extra authors to the destination buffer AuthorList const & extra_authors = options_.settings_from_new ? old_buffer->params().authors() : new_buffer->params().authors(); -- 2.39.2
