Re: [Quickfix-developers] crashes with latest versions, sample code attached ...

[Oren M. <or...@qu...>]

1.12.2 introduced a lot of performance optimizations.  One of the things
being done is that QuickFIX will look for the presence of a better
performaing allocator than the default std::allocator.  My best guess is
there is a bug in the allocator that it is choosing on your system.

When it finds the best one, it will create a definition for it in
config.h.  Possible definitions are HAVE_BITMAP_ALLOCATOR,
HAVE_BOOL_FAST_POOL_ALLOCATOR, HAVE_BOOST_POOL_ALLOCATOR,
HAVE_MT_ALLOCATOR, and HAVE_POOL_ALLOCATOR.

Go through config.h and comment out any of these definitions and see if
your sample application fairs better.  We will probably need to update
the configure script to do a sanity check before deciding an allocator
is viable.  Are your unit tests/acceptence tests passing?
