c++11 - C++ Out of scope delete operator of an object causes crash deallocating std::vector -


i have problem, when try delete manually allocated pointer, causes sigabrt, can't roots of cause. class looks like

class streammetadatareader {  protected:     std::ifstream csvfile;     std::vector<std::string> header;  public:     bool openfile(const std::string& path); };

the object created manually allocating memory using new operator , stored in third party library memory:

auto* reader = new streammetadatareader; vxsetnodeattribute(   node, vx_node_attribute_local_data_ptr, (void *) &reader, sizeof(streammetadatareader *) );

and pointer address passed around functions during program execution. can cast address object type , use properly. @ end of program, retrieve pointer last time , call delete operator free memory so:

streammetadatareader *reader = nullptr; vxquerynode(     node, vx_node_attribute_local_data_ptr, (void *) &reader, sizeof(streammetadatareader *) ); if (reader != nullptr) {     delete reader; }

so debugger says execution stops when default destructor tries free std::vector<std::string> header; object member.

maybe has idea wrong here? know not best practice solution exact problem. maybe use case sort of smart pointer (e.g. weak pointer)?

thanks in advance.

i trying build cypher statement neo4j know 2-n starting nodes name , need find node (if any) can reached of starting nodes. at first tought similar "mutual friend" situation handled (start1)-[*..2]->(main)<-[*..2]-(start2) in case have more 2 starting points around 6 know name. so puzzled how can include third, fourth , on node cypher able find commmon root amongst them. in above example neo4j website need path starting 'dilshad', 'becky' , 'cesar' check if have common friend (anders) excluding 'filipa' , 'emil' not friends of three. so far create statement programmatically looks like match (start1 {name:'person1'}), (start2 {name:'person2'}), (start3 {name: 'person3'}), (main) (start1)-[*..2]->(main) , (start2)-[*..2]->(main) , (start3)-[*..2]->(main) return distinct main but wondering if there more elegant / efficient way in cypher possibly use list of names parameter ...

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
