Hi all.

Sorry if this is a silly question but I can't find the answer into this forun.
How to get the function names in the heaptrc trace ? I use in project options:
in Linking options:
generate debug info for dgb
show line numbers
use symbol file for gdb
use "heaptrc"

in project .pas the very first line is:
   SetHeapTraceOutput(ChangeFileExt(ParamStr(0), '.log'));

File program.log is created ok:

Heap dump by heaptrc unit
3564 memory blocks allocated : 1746202/1754304
3563 memory blocks freed : 1746174/1754272
1 unfreed memory blocks : 28
True heap size : 425984 (96 used in System startup) True free heap : 429024
Should be : 425792
Call trace for block $001F14E8 size 28
/* $0061997C
$0040D5A4
$00411EC1
*/How to get details about the source code generating those memory leaks ?

Antonio.

Hi again.
Got it.
-gl was checked but unchecking "use symbol file for gdb" it works again 8-)

that sounds around correct.

Please test those settings on a dummy project
A simple form, in formcreate, create a new object, and never free it

    TObject.Create;

Maybe test with explicit "dwarf" or "stabs" ?

Your FPC is "as installed" or self compiled?

The first line, looks like it may not be in your code.

It may be there is no info for the $0061... address.

the code that generates the dumps, stops adding line info, once it has failed a single line....

AH,

maybe add a feature request, that this adds a warning, when you set those options....

I confirm:
compiling with "use symbol file for gdb" suppresses line references in heaptrc output
unchecking the checkbox restores line references again. I made a rebuid each time.
Sounds like a bug but I'm not yet sure it is.
