Just out of curiosity? are you doing
multi-threading?

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

I cannot connect the logic
between stack frame #3 and #2; it seems trying to instantiate some global
static data when SIGSEGV happens. Is there some dependency on order of
global static data initialization 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
"boost_serialization-mgw-d-1_33_1.dll" is used here. I saw
some discussion in this mailing list on "Serializing classes defined in DLLs" a year ago, but don't
know what's the current status on it and whether this case is related to it.
Thanks for any hit,
