[Termux] Assertion Failed

by ADMIN 26 views

Introduction

As a Termux user, you may have encountered the frustrating error message "assertion failed" when trying to run certain commands. This issue is particularly prevalent in the new Hangover for Termux, which has been causing problems since version 10.6. In this article, we will delve into the root cause of this issue, explore possible solutions, and provide a step-by-step guide to help you resolve the problem.

Understanding the Error Message

The error message you see is likely:

/home/builder/.termux-build/hangover-wine/src/dlls/ntdll/unix/virtual.c:3421: void *alloc_virtual_heap(SIZE_T): assertion "!(size & host_page_mask)" failed
Aborted

This message indicates that the alloc_virtual_heap function in the virtual.c file has failed due to an assertion error. The assertion checks whether the size parameter is not aligned with the host page mask, which is a critical condition for memory allocation.

Possible Causes

There are several possible reasons why this error occurs:

  • Incompatible patch: It's possible that the issue is caused by an incompatible patch in the Termux build process. This could be a bug in the patch or a conflict with the Hangover code.
  • Hangover issue: The problem might be specific to the Hangover code, which is a wrapper around Wine that allows you to run Windows applications on Linux.

Troubleshooting Steps

To resolve the issue, follow these steps:

Step 1: Check for Updates

First, ensure that your Termux installation is up-to-date. Run the following command:

pkg update && pkg upgrade

This will update all packages, including Hangover, to the latest version.

Step 2: Reinstall Hangover

Try reinstalling Hangover to see if it resolves the issue:

pkg uninstall hangover
pkg install hangover

This will remove the existing Hangover installation and reinstall it from scratch.

Step 3: Disable Hangover

If reinstalling Hangover doesn't work, try disabling it temporarily:

export HANGOVER_DISABLE=1

This will disable Hangover for the current session. If this resolves the issue, you can try reenabling Hangover later.

Step 4: Report the Issue

If none of the above steps work, it's possible that the issue is specific to the Termux build process or Hangover code. In this case, report the issue to the Termux developers or Hangover maintainers, providing as much detail as possible.

Workarounds

While we wait for a permanent solution, here are some workarounds to help you use Hangover:

  • Use Wine directly: You can try running Wine directly without Hangover. This might not work for all applications, but it's worth a try.
  • Use a different wrapper: If Hangover is not working for you, you can try using a different wrapper, such as PlayOnLinux or Lutris.
