Research direction
Start by reviewing the Boost.Iostreams and Bzip2 configuration described for Boost 1.176.0, MinGW-w64 v7, and g++ 10.2 on Windows, then read the linked Stack Overflow discussion about link-time optimization. Reproduce the segmentation fault with that toolchain; done means the LTO build no longer crashes or the issue is narrowed to a documented external defect.
