Hi,<br>
<br>
I've been using boost Serialization library (release v1_33_1) on Linux
without problems, with g++ compiler of both v3.3.6 &amp; v4.1.1.&nbsp;
My program serialzes boost::shared_ptr of polymorphic types, and
BOOST_CLASS_EXPORT() and BOOST_SERIALIZATION_SHARED_PTR() are
used.&nbsp;&nbsp; <br>
<br>
However, when the same program is ported &amp; run on mingw32 (w/ g++
v3.4.5 on WinXP), it generates SIGSEGV before my main() is
called.&nbsp; and here's the stack trace:<br>
<br>
Program received signal SIGSEGV, Segmentation fault.<br>

<br>
<br>
I cannot connect the logic between stack frame #3 and #2; it seems
trying to instantiate some global static data when SIGSEGV
happens.&nbsp; Is there some dependency on order of global static data
initialization&nbsp; to be satisfied for using
BOOST_CLASS_EXPORT/BOOST_SERIALIZATION_SHARED_PTR? HmcBase is the base
class for my polymorphic types, and all my code are statically linked,
while &quot;boost_serialization-mgw-d-1_33_1.dll&quot; is used
here.&nbsp;&nbsp;&nbsp; I saw some discussion in this mailing list on &quot;<a target="_top" href="http://news.gmane.org/find-root.php?message_id=%3c432FF0C3.5010002%40intopii.fi%3e">Serializing classes defined in DLLs&quot;</a> a year ago, but don't know what's the current status on it and whether this case is related to it.

<br>
Thanks for any hit,<br>
