Hello again, Ia currently doing some restructuring on the program that I had probelms with few moths ago. I just poke my editor into some very nasty stuff and I'd like to ask if any of you have any idea why I do get a buch of Invalid pointer error messages.
The program is heavily threaded "MessageDispatch" style of client/server program. The proble is in the server. The server also uses xerces-c++ and sqlite3. I just updated common c++ form 1.0.9 to 1.3.1. None of the threads have final() method defined and the threads are detached() and *not* started(). The invalid pointer error does not appear on 1.0.9 version. I have been using valgrind (altought it's pthread support is incomplete) to find another proble that will crash the program when it tries to create XercesDOMParser. I think these problems *may* be interlinked as the crash occurs in malloc() -> so maybe the TCPSession + other thread stuff messes the memory so that malloc fails. Anyway when the free(): invalid pointer 0xxxxxxxxx! appears Valgrind will display quite many of Invalid read messages like: ==3015== Invalid read of size 4 ==3015== at 0x1BD0E831: ost::Thread::close() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0FA0E: ost::ThreadImpl::ThreadExecHandler(ost::Thread*) (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0E90E: (within /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BCCD847: thread_wrapper (vg_libpthread.c:867) ==3015== Address 0x1BF65B98 is 240 bytes inside a block of size 416 free'd ==3015== at 0x1B90313F: operator delete(void*) (vg_replace_malloc.c:156) ==3015== by 0x8057F87: TCPSessionThread<AgentContainer*>::~TCPSessionThread() (AgentContainer.cpp:125) ==3015== by 0x8057539: ost::TCPSession::final() (socket.h:1725) ==3015== by 0x1BD0E804: ost::Thread::close() (in /usr/lib/libccgnu2-1.3.so.0.0.1) and invalid write messages like: ==3015== Thread 4: ==3015== Invalid write of size 4 ==3015== at 0x1BD0E2EB: ost::Thread::~Thread() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0E82E: ost::Thread::close() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0FA0E: ost::ThreadImpl::ThreadExecHandler(ost::Thread*) (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0E90E: (within /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== Address 0x1BF65B34 is 140 bytes inside a block of size 416 free'd ==3015== at 0x1B90313F: operator delete(void*) (vg_replace_malloc.c:156) ==3015== by 0x8057F87: TCPSessionThread<AgentContainer*>::~TCPSessionThread() (AgentContainer.cpp:125) ==3015== by 0x8057539: ost::TCPSession::final() (socket.h:1725) ==3015== by 0x1BD0E804: ost::Thread::close() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== But the most interesting bit is: ==3015== Thread 4: ==3015== Invalid free() / delete / delete[] ==3015== at 0x1B90313F: operator delete(void*) (vg_replace_malloc.c:156) ==3015== by 0x1BD0E320: ost::Thread::~Thread() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0E82E: ost::Thread::close() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== by 0x1BD0FA0E: ost::ThreadImpl::ThreadExecHandler(ost::Thread*) (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== Address 0x1BF65B34 is 140 bytes inside a block of size 416 free'd ==3015== at 0x1B90313F: operator delete(void*) (vg_replace_malloc.c:156) ==3015== by 0x8057F87: TCPSessionThread<AgentContainer*>::~TCPSessionThread() (AgentContainer.cpp:125) ==3015== by 0x8057539: ost::TCPSession::final() (socket.h:1725) ==3015== by 0x1BD0E804: ost::Thread::close() (in /usr/lib/libccgnu2-1.3.so.0.0.1) ==3015== I am not reserving or freeing any memory (well I do create a new srting that will be deleted elsewhere). Any Ideas? Am I just doing All Things Wrong? Should I consider a career change? I'll provide any additional information you need.
