RThread.Resume crash

[ahti123]

Hello,
anybody has an idea what's wrong with following code:
----
_LIT(KThreadName,"mytesthellothread");
threadObj.Create(
KThreadName,
(TThreadFunction)CHelloWorldBasicAppUi::threadFunc,
0x5000,1000000,2000000,(TAny*)NULL
);
threadObj.Resume();
----

It runs ok on emulator but crashes on device (crashes on Resume() afaik - threadFunc never called)
Symbian 9.1, Series60 SDKv3, GCC-E target

[edit] problematic heap min- and maxsize argument values.Solved.
