i've been seeing this for a while and have only just now gotten around to reporting it... i saw it on my w2k box which is dead now... both this system and that one are/were running identical setups as far as FPC and Lazarus go...

Lazarus 1.3 r42488 FPC 2.7.1 r25797 i386-win32-win32/win64

the following is from starting lazarus with a default blank project and immediately closing lazarus... nothing else is done at all...

Heap dump by heaptrc unit
771193 memory blocks allocated : 74180082/76188624 771194 memory blocks freed : 74180147/76188696 1 unfreed memory blocks : 144
True heap size : 720896 (128 used in System startup) True free heap : 720512
Should be : 720448

it is always at least one block and most of the time of 144 size...

i would post what is in my debug log except that the command line i've been using since years

lazarus --debug-log=lazdbg1.log

doesn't seem to be working any more since i added "-dHEAPTRC_WINDOW" to my build options when building lazarus... how can i re-enable this while keeping the heaptrc window or do i need the heaptrc window if i can get it all written to a log file? i don't know how to do that :/
