Actually it took some time to figure out what's happened

 - add error print if undefined symbol found when generating blob
 - check which symbol is it
 - check Nikolay's repo to find that task_entries get occasionally deleted
   but because it's declared as external in headers the compiler doesn't
   complain but simply yield undefined external reference
