Correction: actully 2GB. Forgot 0th byte.

Was it 32 bit compiler? Because 2GB - 1 byte array would really
be problem with 32 bit programs. But ofcause it should not result in Access 
Violation.

Maybe you got messed up ppu files, or you messed up unit paths.

I found the problem!  It is definitely a compiler bug (compiler did NOT 
report the actual error, all it did was throw an Access Violation).


Unfortunately, I had changed one more line than I remembered during the 
last edit before the failure.


That line was (in the type(s) declaration:

    TAMBytes = array[0..1] of Byte;

I changed it to:

  TAMBytes = array[0..High(Integer)] of Byte;

Type TAMBytes was used as the return type is several functions. When I 
commented out ALL of the code that used TAMBytes, the error went away.  
Since TAMBytes was the only consistent item in that code, I checked its 
declaration and remembered the other :-[ change I made. Reverted that to 
the original version and the compilation succeeded.  Finally changed it to:


  TAMBytes = array[0..32767] of Byte;

This also compiled successfully, and was big enough that it will handle 
much bigger arrays than I expected to use.


I will create a simplified test case and submit a bug report to Free Pascal.

Thanks for putting up with my earlier complaints.

[Lazarus] Compilation aborted!

2018-02-17 Thread Donald Ziesig via Lazarus 

Hi Everyone:

I am writing a package that currently has one unit file which, in turn, 
has two inter-related classes.


Until just now, the package compiled (some empty methods) with only 
expected info and warnings.  I just did some minor editing (added 6 
contiguous lines) and now I get "FATAL Compilation aborted".  I 
commented out the newly entered code, but the compilation aborts.  I 
removed the newly entered code but it still aborts.


I ran the IDE from a terminal and it suggested that I look at the State 
file (.compiled).  I did, but it has nothing of interest.


Can anyone suggest what to do next to isolate the problem?

Thanks,

Don Ziesig
