Error -prod compiling UI example

[paul-reilly]

Describe the bug

Compiling the file (provided further down) works, but when using the -prod flag I get this error:

builder error: 
==================
C error. This should never happen.

This is a compiler bug, please report it using `v bug file.v`.

Expected Behavior

Native compiler to produce a zingy executable.

Current Behavior

Reproduction Steps

The full file, which compiles and runs normally without the -prod flag is:

module main

import ui
import gx

struct State {
mut:
	tb1  string
	tb2m string
	tb3m string
}

fn main() {
	mut app := &State{
		tb1: 'hggyjgyguguglul'
		tb2m: 'toto bbub jhuui jkhuhui hubhuib\ntiti tutu toto\ntata tata'.repeat(1000)
		tb3m: 'toto bbub jhuui jkhuhui hubhuib\ntiti tutu toto\ntata tata'
	}
	lines := app.tb2m.split('\n')
	mut s := ''
	for l in lines {
		s += '${l}\n'
	}
	app.tb2m = s
	c := ui.column(
		widths: ui.stretch
		heights: [ui.compact, ui.compact, ui.stretch, ui.stretch]
		margin_: 5
		spacing: 10
		children: [
			ui.textbox(
				id: 'tb1'
				text: &app.tb1
				fitted_height: true
			),
			ui.row(
				spacing: 5
				children: [
					ui.label(text: 'Word wrap'),
					ui.switcher(open: false, id: 'sw2', on_click: on_switch_click),
					ui.switcher(open: false, id: 'sw3', on_click: on_switch_click),
				]
			),
			ui.textbox(
				mode: .multiline
				id: 'tb2m'
				text: &app.tb2m
				height: 200
				text_size: 24
				bg_color: gx.hex(0xfcf4e4ff) // gx.rgb(252, 244, 228)
			),
			ui.textbox(
				mode: .read_only | .multiline
				id: 'tb3m'
				text: &app.tb2m
				height: 200
				text_size: 24
				on_scroll_change: on_scroll_change
			),
		]
	)
	w := ui.window(
		width: 500
		height: 300
		mode: .resizable
		layout: c
	)
	ui.run(w)
}

fn on_switch_click(switcher &ui.Switch) {
	tbs := if switcher.id == 'sw2' { 'tb2m' } else { 'tb3m' }
	mut tb := switcher.ui.window.get_or_panic[ui.TextBox](tbs)
	tb.tv.switch_wordwrap()
}

fn on_scroll_change(sw ui.ScrollableWidget) {
	// println('sw cb example: $sw.id has scrollview? $sw.has_scrollview with x: $sw.x and y: $sw.y')
}

V version

V 0.3.3 f41ca48

Environment details (OS name and version, etc.)

Linux 6.1.23-1-MANJARO #1 SMP PREEMPT_DYNAMIC x86_64 GNU/Linux

[spytheman]

I've tried v -prod -cc gcc-11 run app.v as well as v -prod -cc clang-12 run app.v on Ubuntu 20.04, and both do work.

What compiler version are you using? Please paste the results of cc --version too.

[paul-reilly]

Thanks for checking, I'm on gcc 12.2.1 and cc is gcc too:

> cc --version

[spytheman]

Try compiling with '-no-parallel' as well.

[paul-reilly]

It's working now with or without -no-parallel. I had ran v up as well, now on v0.3.3 6cc4208.

[medvednikov]

I get the same error periodically. Happens about 2% of the time.

So it's a hard to reproduce bug, but it's there.

@yuyi98 do you know what could be causing

[yuyi98]

Ok, I'll try.

[yuyi98]

It's ok on windows.
