stl vector pop_back() crash

Hi. For some reason I am getting a crash on pop_back() and Im not sure

sorry I cant post the whole code because the vector is used in a bunch
of places.

i have a

vector<bool> complete;

right before i pop back, i set the last element to overwrite on of the
ones in the array.

complete[j] = complete[complete.size()-1];

the crash looks like:
unhandled exception: 0xC00000005 Access Violation reading 0x203f5a34

the size of complete before it crashes is 32, so it is not empty.

the code it crashes on is:
operator bool() const
{ // test if bit is set
return ((*_Getptr() & _Mask()) != 0);


std::vector<bool,std::allocator<bool> >::reference::operator bool()

If anyone has experenced anything like this before, or has some idea
what might be causing the crash, that would be great. thanks!

[vector<bool> problem redacted]

I seem to recall that there was some sort of problem with the MS
implementation of vector<bool>. I know Dr. Plaugher reads this group.

What version of VC are you using?
