Address 0xc00a9553 out of bounds inside stl::vector class

[e2point@yahoo.com]

hi,
i got a program that is suppose to run 24x7x365. However after
functioning for around 15 minutes, it crashes due to a segmentation
fault. program is written in c++ and runs in RH Linux 4. When
inspected one of the parameters of the crashing frame, i get the
following output.

NOTE : c1 is a std::vector

(gdb) pvector c1
elem[0]: $1 = {
static npos = 4294967295,
_M_dataplus = {
<std::allocator <char>= {
<__gnu_cxx::new _allocator<char >= {<No data fields>}, <No data
fields>},
members of
std::basic_stri ng<char,std::ch ar_traits<char> ,std::allocator <char>

>::_Alloc_hider :

_M_p = 0xc00a9553 <Address 0xc00a9553 out of bounds>
}
}

...... and more elements like this ....

according to this out put, _M_p member is not accessible because
address 0xc00a9553 is out of bounds, and the only reason i can think
of is a memory corruption. Is there any other reason for this to
happen.
