Hi,
I'm using purify to check my app.
Using serialization, I see the following FMR:
#################
FMR: Free memory read
This is occurring while in thread 3:
std::locale::~locale() [libstlport.so.1]
boost::scoped_ptrstd::locale::~scoped_ptr()
boost::archive::basic_binary_iprimitive >::~basic_binary_iprimitive()
boost::archive::binary_iarchive_impl
boost::archive::binary_iarchive::~binary_iarchive_impl()
boost::archive::binary_iarchive::~binary_iarchive()
void de::scmb::bm::seri::Serializer::serialize
(std::basic_ifstream&,
de::scmb::bm::core::Instance&)
Reading 8 bytes from 0x100312228 in the heap.
Address 0x100312228 is at the beginning of a freed block of 80 bytes.
This block was allocated from thread 3:
malloc [rtlib.o]
c2n6Fl_Pv___1 [libCrun.so.1]
void*operator new(unsigned long) [rtlib.o]
std::locale::locale(std::_Locale_impl*,bool) [libstlport.so.1]

std::locale*boost::archive::add_facet
(const std::locale&,__type_0*)
[libboost_serialization-sw-d.a]
There have been 0 frees since this block was freed from thread 3:
free [rtlib.o]
c2k6FPv_v___1 [libCrun.so.1]
void operator delete(void*) [rtlib.o]
boost::io::basic_ios_locale_saver

Has anyone seen this before.
Looks like std::locale is using a buffer with 80 bytes size, which is
shared between std::locale objetcs and get deleted by the destruction of
a basic_ios_locale_saver object, which has a std::locale object.
Is this guess correct ??
Can this become a problem ??
Kind regards,
Markus
