Segfaults after upgrade from 8.1.14 to 8.1.15

Description

Hi. After upgrading from 8.1.14 to 8.1.15, segfaults started occurring in code with fibers.
Unfortunately we couldn't make a short reproduction example.

I hope backtrace data from gdb will be enough to understand the problem.

Program received signal SIGSEGV, Segmentation fault.
