You have a few moving parts in the chain here - binutils, gcc, gdb, 
dumper (cygwin), and Windows, that are all being updated asynchronously, 
and have to use and handle features provided by each other, so parts are 
always out of sync, and need tweaked to keep up.
As this is a volunteer project, toolchain internals are complex and 
takes time to understand, comprehension, knowledge, experience are rare, 
and time is scarce, dumper sometimes lags to the detriment of 
debuggability.

WSL adds its own issues. I found if I want to compare (with) Linux 
distros and behaviours, I need to use VMs.
