c++ memory leak in queue initialization -

-

recently company migrated new servers , program no longer worked correctly. compiles ok, when running errors , crashes while initializing queue. using valgrind can see memory leaks in queue library. code bigger have been hard put in here, cut as thought reasonable. think there might problem can't see concerning versions or something, can suggest hints/help?

typedef  unsigned char     byte; typedef  unsigned char     boolean;  typedef  unsigned int      uint32; typedef  unsigned short    uint16; typedef  unsigned char     uint8;  typedef  signed long int   int32;       /* signed 32 bit value */ typedef  signed short      int16;       /* signed 16 bit value */ typedef  signed char       int8;        /* signed 8  bit value */

just type defs next part doesn't confuse

struct mipmsg {     byte           msg[1024];     uint32         msglen;     uint32         ipaddr;     ushort         sin_port;     uint32         mnhomeaddr;     struct timeval ts;     mipmsg() : msglen(0), ipaddr(0), sin_port(0) , mnhomeaddr(0)     {             memset( msg, '\0', sizeof(msg) );     } };  class mipmsgqueue { public:     mipmsgqueue();     ~mipmsgqueue();   private:     queue<mipmsg*>    mqueue_; };

that's h cut h file, , here's cut cpp file.

mipmsgqueue() :: mipmsgqueue() : mqueue_() { }

and here's valgrind snippet. 

==25753==    @ 0x4a0666e: operator new(unsigned long) (vg_replace_malloc.c:220) ==25753==    0x4045c6: __gnu_cxx::new_allocator<mipmsg**>::allocate(unsigned long,        void const*) (new_allocator.h:88) ==25753==    0x4045f9: std::_deque_base<mipmsg*, std::allocator<mipmsg*>    >::_m_allocate_map(unsigned long) (stl_deque.h:424) ==25753==    0x404b23: std::_deque_base<mipmsg*, std::allocator<mipmsg*> >::_m_initialize_map(unsigned long) (stl_deque.h:471) ==25753==    0x404c70: std::_deque_base<mipmsg*, std::allocator<mipmsg*> >::_deque_base(std::allocator<mipmsg*> const&, unsigned long) (stl_deque.h:368) ==25753==    0x404d0d: std::deque<mipmsg*, std::allocator<mipmsg*> >::deque(std::deque<mipmsg*, std::allocator<mipmsg*> > const&) (stl_deque.h:690) ==25753==    0x404e20: std::queue<mipmsg*, std::deque<mipmsg*, std::allocator<mipmsg*> > >::queue(std::deque<mipmsg*, std::allocator<mipmsg*> > const&) (stl_queue.h:146) ==25753==    0x4033e2: mipmsgqueue::mipmsgqueue() (mipmsgqueue.cpp:5)

also here's gdb error code 

 munmap_chunk(): invalid pointer: 0x0000000000621770 ***

thanks reading.

using valgrind can see memory leaks in queue library

memory leaks not (usually) lead crashes. error:

munmap_chunk(): invalid pointer: 0x0000000000621770 *

implies heap corruption, possibly due calling delete on global variable. ignore memory leaks, , other valgrind errors (and invalid free/delete in particular).

css - Which browser returns the correct result for getBoundingClientRect of an SVG element? -

-
this svg contains rect overflows svg element: <svg id='svg' width='10' height='10'> <rect x='-10' y='-10' width='30' height='30'/> </svg> chrome 28 , opera 12 return getboundingclientrect() svg element width , height of 10. firefox 23 reports width , height of 30. correct? jsfiddle the relevant spec cssom , delegates svg spec if svg element not "have associated css layout box". haven't found definition of "having associated css layout box", correct result seem hinge on definition, getbbox returns 30x30 rect in browsers. this firefox bug fixed now, fix in firefox nightlies , should make through firefox 33 released on 14 october 2014. see bug 530985 details.
