Summary

I have a customer who reported a hang in the "jsonsl_feed" function in jsonsl.c file of libbson library. As the customer is not willing to give actual data, I tried to reproduce with dummy data but failed to do so. 

Stack trace of library is 

  address: 0x00007FF5278A5630 ; dladdress: 0x00007FF527896000 ; offset in lib: 0x000000000000F630 ;

Is there any possible reason for this to happen?
Help is much appreciated.
