Crash in conemu-msys2-64.exe #2446

Open sryze opened 2 years ago

sryze commented 2 years ago

Versions

ConEmu build: 210912 x64 OS version: Windows 7 x64 Used shell version (Far Manager, git-bash, cmd, powershell, cygwin, whatever): Git Bash

Problem description

Different processes keep crashing randomly when running Git Bash inside ConEmu. For example, vim.exe, bash.exe, conemu-msys-64.exe. Mostly it happens when I do something with Git, such as git fetch or git push or git status.

It began happening to me recently, but I haven't modified my settings in a few weeks. I've updated Git for Windows to 2.36.1 recently, maybe it's related to that? Although, after I downgraded to 2.35, it still keeps happening.

I attached a stack dump below.

Steps to reproduce

  1. Open a Git Bash tab
  2. Execute some Git commands in a repo (commit, status, push, etc)

Actual results

Active ConEmu tab freezes, Ctrl-C is not working. Sometimes it creates a .stackdump file, sometimes not.

Expected results

Expected ConEmu / Git Bash to not freeze/crash

Additional files

Settings, screenshots, logs, etc.

Update:

bash.exe crash:

My Git Bash task is started using this command:

set "PATH=%ProgramFiles%\Git\usr\bin;%PATH%" & %ProgramFiles%\Git\git-cmd.exe --no-cd --command=%ConEmuBaseDirShort%\conemu-msys2-64.exe /usr/bin/bash.exe -l -i -new_console:p

This started happening to me tonight while I was doing heavy compiling (100% CPU usage across 8 cores) and various pip installs. Specifically, ConEmu will stop handling input and output completely in a single tab //while the foreground task I started from the shell continues to run//, according to Task Manager. Downgrading msys2-runtime from 3.3.5-1 to 3.3.4-2 temporarily seems to have solved the ConEmu freezing.

I do not have a stackdump or other files to share right now; mostly commenting while the changes I made to my environment are still fresh in my mind. conemu-msys2-64.exe does not appear to be crashing, just refusing to send/receive output/input at all.

@cr1901 Were you able to solve this? I've reinstalled both ConEmu and Git Bash (tried earlier versions as well) and still experiencing the crashes... Not sure what else can be done. Regular Git Bash console (MinTTY) is working fine for me.

sryze commented 2 years ago

After I re-installed both Git and ConEmu, the crashing occurs much less often. Although it does happen from time to time. But at least I can use ConEmu now.

cr1901 commented 2 years ago

@sryze Yea, sorry, I have not had time to solve this or try to duplicate. I have my own detailed notes on when things stopped working though, so I can attempt a bisect to find out when things started failing when I'm up for it.

sryze commented 1 year ago

Looks like some change in Git for Windows / Git Bash is causing this. After I upgraded to 2.37 ConEmu began crashing again.

delroyhiebert commented 5 months ago

I just started encountering this after updating git for windows. Git version 2.43.0.windows.1 and conEmu version 230724

Unfortunately I didn't think to note what version of git I came from, but I hadn't updated git in probably two or three years.

I haven't done any additional investigation yet, but will if I can find the time.
