Strange message from lfortran without the "-o" option

[angelog0]

$ lfortran --version
LFortran version: 0.59.0
Platform: Windows
LLVM: 21.1.8
Default target: x86_64-w64-windows-gnu
LSP Version: 3.17.0
JSON_RPC Version: 2.0

$ lfortran test.f90
"." non è riconosciuto come comando interno o esterno,
 un programma eseguibile o un file batch.

and test.out is created. The message is non displayed using lfortran test.f90 -o test, in which case, test.exe is created.

Using GFortran:

gfortran test.f90

No message and a.exe is created.

Is this to be expected for lfortran?
