termux: hot reload example segmentation fault

[7underlines]

Describe the bug

Execution of the command v -live run examples/hot_reload/message.v prints segmentation fault.

Expected Behavior

The example works.

Current Behavior

v -live run examples/hot_reload/message.v
OK reloads:    0 | Total reloads:    0 | Hello! Modify this message while the program is running.
signal 11: segmentation fault

Reproduction Steps

v -live run examples/hot_reload/message.v

Possible Solution

I found that it works with the -cg parameter.

v -cg -live run examples/hot_reload/message.v
OK reloads:    1 | Total reloads:    1 | Hello! Modify this message while the program is running.

It's been two years and hot reboot still doesn't work on windows

@andorxornot I'm sorry to hear this because I think hot reload is one of V's best features. Have you tried the -cg parameter? Because with this workaround it works under Termux.

[andorxornot]

@thomaspeissl just tested on the latest master, the problem remains, with or without cg parameter v output:

[andorxornot]

could you also check the graphical examples of hot-reload? for example v -live run examples/hot_reload/bounce.v

@andorxornot I recommend you create a separate issue for Windows.
