First and foremost consider this:

  • Only RetroArch bugs should be filed here. Not core bugs or game bugs
  • This is not a forum or a help section, this is strictly developer oriented


Entering nothing(or just blank) in connect to netplay hose causes segfault.

Expected behavior

should just return to netplay menu when server(or host address) is invalid or not available or similar.

Actual behavior


Steps to reproduce the bug

  1. run RA, launch game
  2. goto quick menu, goto Netplay
  3. choose connect to netplay host
  4. enter nothing, or leave it blank
  5. press Enter on keyboard or button 1 in gamepad(whichever is set to OK)
