Re: Segmentation Fault Issue in PostgreSQL 13.4

have encountered similar issues in my own code when developing C
extension. Root cause is very likely a bug in the cause_segfault() C
function.
You should compile your C code in debug mode and use debugger to check what
invalid memory access you have in your code.
