Re: [fpc-devel] fpc 2.6.2 - heaptrc and dwarf will crash
It appears heaprc has another problem; if the RTL (and therefore heaprc) is
compiled with OVERFLOWCHECKS enabled (i.e. -Co) it blows up when the
aggregate of memory allocations made by a thread exceeds 4GB (the size of
32 bit allocation variables, e.g. getmem8_size).
Does this perhaps suggest that this file should specify
{$PUSH}{$Q-}...{$POP} at the appropriate places to avoid this problem?
Otherwise, a program with the heap tracer enabled running with an RTL built
with this check enabled will throw an overflow exception eventually.

[fpc-devel] fpc 2.6.2 - heaptrc and dwarf will crash
It seems that in FPC 2.6.2 the dwarf reading code in LnfoDwrf is broken.
It always gives a run-error 131
compiled below example with
-MObjFPC -Scghi -O1 -gw2 -gl -gh -vewnhi
and boom
program Project1;
{$mode objfpc}{$H+}
begin
TObject.Create;
end.
it prints
Heap dump by heaptrc unit
1 memory blocks allocated : 4/8
0 memory blocks freed : 0/0
1 unfreed memory blocks : 4
True heap size : 98304 (112 used in System startup)
True free heap : 98112
Should be : 98120
Call trace for block $00087458 size 4
$00401427 line 6 of project1.lpr
and then 131 is risen
