Hi,
Is it the line with InterlockedExchange() call? The reason I ask, I'm
using FPC 2.4.3 under 64-bit linux and using fpGUI. All other
platforms has a clear 'IsMultiThreaded := True' in the RTL code, but
not for Unix. It seems CheckSynchronized() is never called in
fpGUI/X11 because IsMultiThread is never True, even though I have
'cthreads' unit defined as the first unit in my fpGUI program.
-------------[ rtl/unix/cthreads.pp]------------------
....
{ Initialize multithreading if not done }
if not IsMultiThread then
begin
if (InterLockedExchange(longint(IsMultiThread),ord(true)) = 0) then
begin
{ We're still running in single thread mode, setup the TLS }
pthread_key_create(@TLSKey,nil);
InitThreadVars(@CRelocateThreadvar);
end
end;
....
-------------------------------
In fpGUI, CheckSynchronized is executed as follows in the main event loop.
....
if IsMultiThreaded then
CheckSynchronized();
...
