Error building on Alpine (on Windows builds ok)

[lospejos]

When I try to clone and build gitly on Alpine Linux 3.18 using v version: V 0.4.0 3c26bff, I get errors:
F.e.:

/src/feed_service.v:14:23: error: exec() returns a Result, so it should have either an `or {}` block, or `!` at the end
   12 |     where_repo_ids := repo_ids.map(it.str()).join(', ')
   13 |
   14 |     commits, _ := app.db.exec('
      |                          ~~~~~~
   15 |         select author, hash, created_at, repo_id, branch_id, message from `Commit`
   16 |             where repo_id in (${where_repo_ids}) order by created_at desc
/src/feed_service.v:20:16: error: invalid variable `commits`
   18 |     mut item_id := 0
   19 |
   20 |     for commit in commits {
      |                   ~~~~~~~
   21 |         vals := commit.vals
   22 |         author_name := vals[0]
/src/feed_service.v:21:18: error: `commit` does not return a value
   19 |
   20 |     for commit in commits {
   21 |         vals := commit.vals
      |                        ~~~~
   22 |         author_name := vals[0]
   23 |         commit_hash := vals[1]

etc
Compiler used on Alpine Linux: -cc gcc

At the same time, on Windows 10 the same repository builds successfully using v version: V 0.4.0 320057d and tcc compiler.

Probably compiler (gcc vs tcc) is the errors' cause?

I'm not an expert in C compilers etc, so I may be wrong.

Appreciate any help!
