Hi Jorg,<div><br></div><div>Nice job, I tried the head of DCMTK, and the OfCondition crash disappeared. <div>However I'm experiencing another crash. I can reproduce in my small program (ofConditionCrash) and in the test application ctkDICOM in CTK.</div>
<div><br></div><div>This is very odd, a static OFList is instantiated twice with the same address and deleted twice at the same address, therefore a crash. See below the backtrace when I place a breakpoint in OFList() and ~OFList(). Note that the address is always the same (0xa6ea70). Btw, the address is a 32bits address, does it mean DCMTK is built in 32bits ?</div>
<div><br></div><div>I tried with a clean build of CTK. Can you eventually try that CTK branch <a href="https://github.com/finetjul/CTK/tree/dcmtk-trunk">https://github.com/finetjul/CTK/tree/dcmtk-trunk</a> and see if you have a crash when running ctkDICOM ?</div>
<div><br></div><div>Thanks,</div><div>Julien.</div><div><br></div><div>At startup:<br><br>First time the OFList at address 0xa6ea70 is constructed:<br><br>Breakpoint 1, OFList<DcmCodecList*>::OFList (this=0xa6ea70)<br>
