In such case, write a small testcase.
I did it for you. I made a copy/paste of your snippets in a single 
source file, plus some glue (see attached file).

For me, it works perfectly. I cross-compiled the source using gcc 4.3.3 
and I ran it on Steem (nearly perfect STe emulator - of course without 
FPU !)

m68k-atari-mint-g++ vect.cpp -o vect.tos

(go to the emulator)

vect
Not crashed ! screenname = bcdef

Try this source on your system to check it is not a compiler issue.
I really think your problem is elsewhere.
Maybe you trashed the stack before calling push_back ?
