Code inspection not returning expected result


I’m trying to use the code inspection tool for my ESP32 code. I created a simple test with some obvious errors that I thought should be caught. The problem is the inspection tool doesn’t return the visual information that I see in most examples for the tool. It just returns a long list of text and doesn’t seem to find any problem with my code.

void setup() 
  int *x = (int*)malloc(10);
  *x = 123;

This is the screen that I get:

When I inspect the whole message by using the CLI and executing pio check it has

Error: Found a breaking defect 'syntax error' in C:\Users\Max\.platformio\packages\toolchain-xtensa32@2.50200.97\xtensa-esp32-elf\include\c++\5.2.0\bits\random.h:69
Please note: check results might not be valid!
Try adding --skip-packages

at the end.

When I execute pio check --skip-packages I get

So it catches the double-free and dereference-freed-pointer issues.

It’s a known error that cppcheck just dies when analyzing some toolchain or SDK files :frowning: (see e.g. cppcheck code inspect fails on samd boards · Issue #3951 · platformio/platformio-core · GitHub)

--skip-packages works around that by not telling it to do that.

Thanks, I get the same result now.

This can only be run by CLI? Is there an option to add --skip-packages to the visual inspector?


This setting is not exposed UI as far as I know. I’ve opened an issue for that here.
