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. > This is a pain in the butt, but it is what it is.

I found if I want to compare (with) Linux distros and behaviours, I need to use VMs. -- Take care.
