How to debug D on Linux

[evilrat]

if you are looking for back trace someone recently posted a hint 
for linux where there is no back trace by default is to import 
core.sys.linux.backtrace or something that has back trace info 
and using it in exception handler for runtime to print the stack 
trace.

no idea what is -d-debug, but -g will emit debug info for 
debugger, and -debug will turn on certain features such as 
contracts and asserts even in release builds.
