Hi, reading a TTree with the Win debug version of Root I get the following error: --- <CustomReAlloc2>: passed oldsize 64, should be 589833 Fatal in <CustomReAlloc2>: unreasonable size (589833) aborting Warning in <TWinNTSystem::StackTrace>: this method must be overridden! --- The call stack is as follows: --- [...] Fatal(const char * 0x00ba3168, const char * 0x00ba31c8) line 186 + 22 bytes CustomReAlloc2(void * 0x016b2c00, unsigned int 1024, unsigned int 64) line 369 + 37 bytes TStorage::ReAlloc(void * 0x016b2c00, unsigned int 1024, unsigned int 64) line 182 + 18 bytes TObjArray::Expand(int 256) line 287 + 29 bytes TObjArray::Streamer(TBuffer & {...}) line 307 TBranch::Streamer(TBuffer & {...}) line 1044 TBuffer::ReadObject(const TClass * 0x0161a1f0) line 1321 LIBCORE! operator>>(class TBuffer &,class TObject * &) + 17 bytes TObjArray::Streamer(TBuffer & {...}) line 310 + 13 bytes TTree::Streamer(TBuffer & {...}) line 2769 TKey::ReadObj() line 474 [...] --- It fails trying to stream the 16th of 256 objects (an TObjArray) within the fourth of 16 branches. Could the problem be caused by some incompatibility between the debug version of "::new" and the debug version of ReAlloc? MSVC tells me --- HEAP[ntpl2classDbg.exe]: Heap block at 01129E70 modified at 0112C458 past requested size of 25e0 --- Cheers, Axel.
