I’m trying 4.23.1, because I want to test pixel streaming for Linux:
I got the following SIGSEGV and assertion failure:

Engine crash handling finished; re-raising signal 11 for the default handler. Good bye.
Segmentation fault (core dumped)
I can’t tell which one is the cause of the failure, the assertion or the segmentation fault.
there was a memory access at address 0x3
Unhandled Exception: SIGSEGV: invalid attempt to write memory at address 0x0000000000000003
Anybody saw the same?
