[IGSTK-Users] Error in Release mode, not in Debug mode

[Tamas Ungi]

Hi Patrick,

Yes, the main function begins with igstk::RealTimeClock::Initialize();
I have inserted text outputs in igstkPulseGenerator.cxx, and found out that
the line:
(t->cb)(t->arg);
around line 445 in igstkPulseGenerator.cxx doesn't return, but hangs. The
first time it is called.

Thanks,
Tamas

Hi Tamas,

Do you have the following line in the beginning of your code?

igstk::RealTimeClock::Initialize();

In release mode, all uninitialized memory are set to zeros. This could be
the potential reason of failing.
