Description hkoba 2021-10-06 05:02:41 UTC 
Description of problem:
1. Launch RStudio (rstudio-desktop-1.4.1717-2.fc34.x86_64)

2. Open new Rmd

3. Turn ibus-mozc on and Enter multilingual texts like Japanese hiragana.

Then, ibus-mozc dies with SEGV at  mozc::ibus::(anonymous namespace)::GetSurroundingText(_IBusEngine*, mozc::ibus::SelectionMonitorInterface*, mozc::ibus::(anonymous namespace)::SurroundingTextInfo*) [clone .part.0] [clone .constprop.0] (engine=<optimized out>,

Sorry, this is not a SEGV, but an uncaught length checks error of std::string, as you can see.

Following is what I saw in "coredumpctl debug"

This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '34'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

I tested with mozc-2.26.4577.102-2.fc36.x86_64 and looks good unless I'm not missing anything. please try again with the latest version and reopen if this still persists. thanks.
