Is this on 32 or 64 bits windows ? Do you know if your customer uses
only numpy, or other packages that depend on numpy C extension ?

It is 64 bit Windows. <br>
I forgot to say that a part of my numpy arrays are generated by a
short <br>
Cython method wrapping open-ms library.<br>
<br>
As the code fragment is short, I post it here:</tt><tt><br>
</tt>
<blockquote><tt>def get_peaks(self): <br>
<br>
</tt><tt> cdef _MSSpectrum[_Peak1D] * spec_ = self.inst<br>
<br>
</tt><tt> cdef unsigned int n = spec_.size()<br>
</tt><tt> cdef np.ndarray[np.float32_t, ndim=2] peaks <br>
</tt><tt> peaks = np.zeros( [n,2], dtype=np.float32)<br>
</tt><tt> cdef _Peak1D p<br>
<br>
</tt><tt> cdef vector[_Peak1D].iterator it = spec_.begin()<br>
</tt><tt> cdef int i = 0<br>
</tt><tt> while it != spec_.end():<br>
</tt><tt> peaks[i,0] = deref(it).getMZ()<br>
</tt><tt> peaks[i,1] = deref(it).getIntensity()<br>
</tt><tt> preincrement(it)<br>
</tt><tt> i += 1<br>
<br>
</tt><tt> return peaks<br>
</tt></blockquote>
<tt>I am sure that this functions does not crash during execution.<br>
As spec_ 's class is derived from C++ STL std::vector<..>
there should<br>
be no conflict between counting 'i' up to 'n' and testing 'it'<br>
against 'spec_.end()'.<br>
<br>
