FBC Compiler error

@Clippy:
-> is the pointer dereference operator.
Like the period is used to access the parts of a type.
If you are accessing the points of a type ptr, then you use ->

Code:

Type test     a as integerend typedim variable as testdim variable_ptr as test ptr'@ means Address ofvariable_ptr = @variablevariable.a = 4print variable_ptr->a

QB uses >=. FB uses -> ? That don't sound right

I used it like this

Code:

const packSize as integer = 5type dog dim age as integerend typedim pack(1 to packSize) as dogdim oldest as dog ptr'... blah blah blah, do stuff with dogs' ages'Find oldest dog in packoldest = @pack(1)for i as integer = 2 to packSize 'compare age if oldest=>age < pack(i) then oldest = @pack(i)next iend

Still, you might want to send the source causing that problem to the devs. It could be indicative of a legitimate problem with the compiler.

It went away after I fixed some syntax errors. I was typing => instead of ->. Still, that was odd since the compiler didn't flag that as an error.

That's an error in the compiler itself. It means the compiler is trying to access memory it doesn't have access to, and it's bailing. Likely a buffer error.

I got an error message "Aborting due to runtime error 12 ("segmentation violation" signal)" when I tried to compile something. It didn't give a line number or anything, it just says that. What does it mean? Is the code I'm trying to compile bringing up the error, or is the compiler itself having the error?
