Hello,

uses
  classes;
var
  l: tstringlist;
begin
  l.loadfromfile('file.txt'); //<-hangs here
  ...
end.

Program hangs (under windows, 1.9.2 and earlier v.) then i try to load relatively large file (~7 MB) without raising any error message. It works ok, if i set more memory using directive ($M). Why do not program allocate neaded memory automaticaly? Do i need to calculate how much memory need to program and set its size before compilation always?

No. Are you sure it hangs ? My guess is that it is simply working very hard. It only allocates a 1K buffer to load the file, so that should not be the issue.

I submitted a bug in the FPC bug list (as #3061).
I would discuss it a little because now I write a stuff to radically solve problems with indexes export. Maybe, these two problems need to be solved as one complex? But I'm understandig that big changes in the compiler code may cause new problems.

Sincerely, Pavel.

Description:
FPC doesn't support exports clause in units. That breaks Delphi compatibility and may cause serious problems by writing or porting big library projects.

unit unit1;
interface
implementation
procedure MyProc;
 begin
 end;
exports
 MyProc name 'MyProc';
end.
library myLib;
uses
 unit1;
begin
end.

I don't think that it creates new problems. It is a part of the compiler that is rather independent from other functionality. If you can are working on a fix please take also a look at the next problem reports:
