Bug ID: 165489
Summary: LibreOffice crashes while the WritingTool extension is
running
Product: LibreOffice
Version: 25.2.0.3 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
The problem seems to occur in the interface. The trigger is probably a problem
in the extension. But since the main application does not send an exception but
crashes itself, the error cannot be found in the extension. For the error
message when the application crashes, see below.
Background: WritingTool is an extension written in Java that mainly performs a
grammar check. Since it operates not only at the level of sentences and
paragraphs, but also on the entire text, various LO interfaces are used.
I have two concerns:
1. An extension should not crash the main program. That is a bug. Instead, an
exception should be sent to the extension via the interface. The extension can
then react to it accordingly.
2. I need a hint as to which interface is causing the problem to be able to
find the problem in the extension's code. Can anyone tell from the error output
below which interface it is?
The Error output on console:
terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string_view::substr: __pos (which is 310) > __size (which is
292)
terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string_view::substr: __pos (which is 30) > __size (which is
20)
Fatal exception: Signal 6
