Toggle Menu in-game from controller then select resume crashes Retroarch

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

Description

When I toggle the retroarch quick menu from Hotkey+Select, if I try to resume content it hard crashes RetroArch and game content freezes.

Expected behavior

RetroArch should be able to resume game Content and not freeze.

Actual behavior

RetroArch does a hard crash and you cannot exit the game content.

Steps to reproduce the bug

1. Use these relevant config settings in retroarch.cfg:

# This is the ps3 controller select button.
input_enable_hotkey_btn = "0"
# This is the ps3 controller start button.
input_exit_emulator_btn = "3"
# ps3 controller home button.
input_menu_toggle_btn = "16"

2. Start game.
3. Press Select + Home (to get into retroarch quick menu).
4. Select the Resume Content option and it should hard crash.

Version/Commit

Environment information

EmuElec version: 4.2

Start by reproducing the crash in RetroArch 1.9.4 with the provided retroarch.cfg controller mappings and the Select + Home sequence. Trace the quick-menu Resume Content path; done means content resumes without crashing or freezing and the emulator remains controllable.
