Subject Re: help needed: heap corruption when activemq-cpp routines called
Date Wed, 14 Jul 2010 02:35:15 GMT

I have the same problem. Here is the solution:
when in debug mode, use activemq-cppd.lib(don't use activemq-cpp.lib:
crash);when in release mode, use activemq-cpp.lib(don't use
activemq-cppd.lib)。
