Martin Carpella commented on AMQCPP-303:
----------------------------------------
I double-checked the cross-compile scripts, yes, it's 3.2.2 and no longer
3.2.1. I'm still trying to get a meaningful backtrace from gdb, but the device
hasn't got enough memory to load all symbol files involved and I'm having
issues with remote GDB and library resolution. As soon as I can get this to
work, I'll post the backtrace.
> SEGFAULT on startup (before main)

> Project: ActiveMQ C++ Client
> Issue Type: Bug

> Application linked with activemq-cpp library crashes on startup before

> The issue is that static globals are being initialized and calling apr
> library functions during that initialization before apr initialization is
> called (via DecafRuntime()). The DecafRuntime object has a singleton
> initialization pattern which appears to be invoked from
> Runtime::initializeRuntime(), which is invoked from
> ActiveMQCPP::initializeLibrary() in turn from the main routine with stdargs.
> To fix this, static initializers should contrive to call at least
> Runtime::getRuntime() (and possibly other initializers invoked by
> initializeRuntime()) before internally initializing. Alternatively, static
> const elements could be handled via the singleton initialization pattern as
> well such that they aren't initialized until needed... presumably after
> ActiveMQCPP::initializeLibrary() has been invoked in a deterministic manner.
> The offending static initializers in this case are from
> decaf/net/InetAddress.cpp:
> const InetAddress InetAddress::LOOPBACK( Inet4Address( "localhost",
> InetAddress::loopbackBytes, 4 ) );
> const InetAddress InetAddress::ANY( Inet4Address( InetAddress::anyBytes, 4 )
> );
