GambasTester will pass, but when you close main form, signal 11 will rise.
Commenting out Free(pp) from mTest: line 1070, will prevent crash.

True, and that is my only usage for them,
except GambasTester which is supposed to test every command
for possible errors.

Aaaa... of course, pointer is not correct to free after pp += 4.
Though, result shouldn't be signal 11.
It could not be different.
I mean Gambas should handle this without crash,
but of course this is anyhow end of execution.
I still would like to see error message with according line
Jussi i can post here the cases of pointer's mis-usage from my book and
you can add any of them in your project freely.
1) Assign new address to an existing pointer drives to memory leak.
The first address cannot be freed directly.

:) Pointers are tricky!
And may be this subject is difficult for BASIC programmers like me.
But in time we can learn their tricks and pay attention to such cases.
In my book i simulate and describe such cases based on

yes, the ability to avoid pointers is one of the main advantages of
higher-level languages like Gambas.
I'm curious to know why you guys are so fascinated by them, other than
interfacing

For me i just want to describe them for my book about Gambas3, that's
all. In this, is including the tricky part of pointers and the correct
use of them inside a program.
