App crashes on pthread_mutex_init (BigSur Beta, ARM)

Hello,
We have application which works fine on macOS 10.13-11.0 with x64 architecture and in Rosetta2 on ARM. But the same code rebuilt for ARM64 caused to SEGV on
Code Block
pthread_mutex_init.


Part of crash report:

Maybe some additional code needed for ARM64 platform?

P.S. We have boost 1.70.

In our legacy code we had
Code Block language c
#pragma pack ( push )
#pragma pack ( 1 )

before and

Code Block language c
#pragma pack ( pop )

after CTcpThread class declaration. So, problem was in legacy code with memory alignment preprocessor directives.
These directives were added in year 2011 originally for Linux, but without #ifdef ____linux____ somewhy.
