Bus error (core dumped) after restart - corrupted binary #3750

Description:

The opencode binary was working correctly in a previous session. After quitting and starting a new session, it now immediately crashes with a "Bus error (core dumped)" message. This suggests a potential corruption issue that occurred between sessions.

Analysis of the binary and the resulting core dump indicates that the executable is now corrupted.

Steps to Reproduce:

1. Use opencode successfully in a terminal session.
2. Quit the session.
3. Start a new terminal session.
4. Run the opencode binary again.

Expected Behavior:

The opencode application should start and run as expected in the new session.

Actual Behavior:

The application crashes instantly with the following error:

Bus error (core dumped)

System Information:

• OS: Debian GNU/Linux
• Architecture: x86_64
• Kernel: Linux inspiron7572 6.1.0-40-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.153-1 (2025-09-20) x86_64 GNU/Linux

Technical Details & Logs:

1. File Analysis: The file command suggests the binary has missing section headers.

   $ file /home/nileshevrywhr/.opencode/bin/opencode
   /home/nileshevrywhr/.opencode/bin/opencode: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, missing section headers at 104403168
   

2. GDB Backtrace: A backtrace from the core dump shows the crash occurs inside the dynamic linker (ld-linux-x86-64.so.2) while trying to process the ELF file. gdb also fails to recognize the executable format.

   Core was generated by `opencode'.
   Program terminated with signal SIGBUS, Bus error.

This evidence strongly suggests the binary is malformed, preventing the system's dynamic linker from loading it correctly. The likely solution is to rebuild and redistribute a valid binary.
