Re: [Cppcms-users] SV occurs at json_rpc_server::return_result(cppcms::json::array()) with aio::io_service

[CN <cn...@fa...>]

The actual json::array passed to boost::bind() is a nested "deep"
object, like so:

void m2(booster::shared_ptr<cppcms::rpc::json_call> requester
		,int size,const cppcms::json::array &ja)
{
	cppcms::json::array a;
	a.resize(3);
	a[0]=cppcms::json::array();
	a[0].array().push_back("a");
	a[0].array().push_back(1);
	a[1]=cppcms::json::array();
	a[1].array().push_back("b");
	a[2]=cppcms::json::array();
	a[2].array().push_back("c");
	ja.push_back(a);
	io_service.post(boost::bind(&report_service::m1,this,requester,size,ja));
}

After restructuring my code, gdb now reports the location of segment
fault at line# 280 in json.cpp:

memset(&m,0,sizeof(m));

If I comment out this line, my progam does not crash here any more.

My question now is:

With the line
static_cast<array *>(ptr())->~array();
in place, is it necessary to call memset()?

Best regards,
CN
