Hi,
I am using this extension and having problems with debugging. Everything works perfectly when my code size is small, I can debug and step through no problem, including with multiple source files. However, when the code gets larger debugging stops working, the output in debug console is:

==================== Initialize ====================


==================== Connect ====================

[SEND]: set print elements 0

[END]
[SEND]: set width 0

[END]
[SEND]: file "debug/debug.elf"
    Reading symbols from debug/debug.elf...
    done.
[END]
[SEND]: target extended-remote localhost:3333

    Continuing.

[END]

My launch.json file is:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "stm8-debug",
            "request": "launch",
            "name": "sdcc launch",
            "serverType": "stm8-sdcc",
            "executable": "debug\\debug.elf",
            "cpu": "STM8L101K3T",
            "port": "3333",
            "openOcdConfigs": [
                "interface/stlink.cfg",
                "target/stm8l.cfg"
            ]
        }
    ]
}

Again, everything works for smaller programs but it seems to hit a critical point where it stops working. If required I can get a simple example set up where add a few instructions changes it from working to broken.
