Retroarch crashes when adding roms from archives

Description

When adding games from an archive (I tested 7z and Zip so far), Retroarch crashes without any error.
This happened beginning with version 1.22.0 while scanning 7zip or Zip files for ROMS.
These archives are not corrupted and I was able to extract them normally to test this.

However, on version 1.21.0, scanning the same compressed archives worked.

Expected behavior

Scanning compressed archives are added to the according playlist and Retroarch doesn't crash.

Steps to reproduce the bug

1. Have Retroarch 1.22.2 installed
2. Try to add ROMS from a highly compressed 7z or Zip file containing ≈800+ files
3. Retroarch crashes after a certain amount of scanned files

Relevant log output

Start by reproducing the crash on macOS with RetroArch 1.22.2 using a highly compressed 7z or Zip archive containing about 800 files, noting that no log output is provided. Compare the scan with version 1.21.0 and investigate the regression between those versions. Done means archive scanning completes without crashing and the ROMs are added to the appropriate playlist.
