Description
Environment
- OS and version: Windows 10
- VS Code: 1.98
- C/C++ extension: 1.23.6
- OS and version of remote machine (if applicable):
- GDB / LLDB version: GDB 11.1
Bug Summary and Steps to Reproduce
Bug Summary:
When initiating a debug session in Visual Studio Code with pre-set instruction breakpoints, the disassembly view does not load as expected. the disassembly view has a "disassembly not available" in the window.
Steps to reproduce:
- Start any debug session in Visual Studio Code.
- Open the disassembly view.
- Set instruction breakpoints in the code.
- Stop the debug session.
- Start the debug session again (while the instruction breakpoints are still set).
- Open the disassembly view.
- Observe that the disassembly view will not load correctly and will display a "disassembly view not available"
message.
Debugger Configurations
you can try any debug configuration
Debugger Logs
I don't have the logs, but if you try to reproduce you will see that when trying to start a debug session with a pre-set instruction breakpoint, you will get a disassembly request of size 1 which I assume is what cause the bug.

Research direction
Reproduce the issue in VS Code 1.98 with the C/C++ extension, GDB 11.1, any debug configuration, and a pre-set instruction breakpoint. Compare the disassembly request during the second session, especially the reported size-1 request, and confirm that the disassembly view loads instead of showing “disassembly not available.”
