Executable have problems with DWARF debug information
We're compiling production code with GHC 8.2.2 under Windows 10 (i.e. Mingw64). A crash occured during one of our FFI bindings and we wanted to use latest GHC debugging functionallity to find the problem faster. We used a tool cv2pdb to convert DWARF information into PDB, but we hit a crash with the tool - https://github.com/rainers/cv2pdb/issues/23 In response, the tool author brought us back a output of a problem in objdump tool over our executable:
