[fpc-devel] Memory leak on BeginThread() when RTL compiled with -O2

Answer for my previous message

Memory leak happens when unit 'rtl\win32\sysinitpas.pp' compiled with
"-O2" or higher.
To eliminate this bug add "-O-" or "-OoNOREGVAR" to command-line when
compile this unit. This disables optimizations when enabled in 'fpc.cfg',
e.g:

%FPC_COMMAND% -O- -Mobjfpc win32\sysinitpas.pp

or

%FPC_COMMAND% -OoNOREGVAR -Mobjfpc win32\sysinitpas.pp
