So what is wrong with this code then... When I quit the app, it says
I have one memory leak. What am I not freeing?
If you compile the rtl with line info, you'll see the non-freed object
is in the RTL:
Call trace for block $00187260 size 60
$0000E284 line 180 of /Users/jonas/fpc/rtl/inc/objpas.inc
$0000F070 line 724 of /Users/jonas/fpc/rtl/inc/objpas.inc
$00052158 line 16 of /Users/jonas/fpc/rtl/objpas/sysutils/sysuthrd.inc
$00039F0C line 1658 of /Users/jonas/fpc/rtl/objpas/classes/classes.inc
Line 1658 of classes.inc is
GlobalNameSpace := TMultiReadExclusiveWriteSynchronizer.Create;
in the procedure CommonInit. In CommonCleanup it does:
{ GlobalNameSpace is an interface so this is enough }
GlobalNameSpace:=nil;
but apparently this is either not enough, or there is a bug with
interface reference counting (the latter is possible, since I've read
more things about that lately).

Graeme, if you use fpc 2.1.1, then memleak of 40 bytes is not your fault.
