Run-time error calling MyByRefFunc($map["foo"].bar) ==> Expected a variable in user function call

[nurupo]

The following causes a run-time error:

Global $map[], $submap[]
$submap.bar = 0
$map["foo"] = $submap
foo($map["foo"].bar) ; ==> Expected a variable in user function call.:

Func foo(ByRef $var)
EndFunc

You have to use [] and then dot notation to reproduce the error. [] and [] works and doesn't result in error.

Using a dot notation and then [] also results in the error, i.e.:

foo($map.foo["bar"])

This seems to be an issue of operator precedence, as putting () to force the left-most element to get extracted first doesn't result in any run-time error, i.e.:

foo(($map["foo"]).bar)

and

foo(($map.foo)["bar"])

respectably.

(Note that declaring the function before it is used results in an AU3Check instead, not a run-time error, which supposedly was fixed in 3.3.16.1 but I'm still experiencing it: ​https://www.autoitscript.com/trac/autoit/ticket/3902#comment:3)

EDIT: this is indeed an AutoIt3 internal issue..

I'm a bit confused with your reply. You have linked to the Au3Check.exe, but this is a run-time issue, the application runs and then crashes after encountering this issue, it's not the Au3Check.exe linter issue. The one in 3902 is the linter issue, but not this one.

Ah yes, you are right ... sorry about that and will correct my answer.
