Most reliable debugging experience for LDC

I've tried to get de-mangling, line numbers and local variables working on OS X and Linux using both GDB and LLDB (multiple versions). My target is compiled with -g. So far, none of the variants work across all areas, although some produce de-mangled names and others produce line numbers (but mangled names).

I believe none of the variants produced local variables - OS X might have done under one configuration but currently I need to debug a live process on Linux. This is the most important part for me, because I can piece together the other information from other debugger executables if really necessary.

I have recently tried LLDB 3.4.2, LLDB 3.8, GDB 7.6.1 and GDB 7.11. LDC was compiled with LLVM/Clang 3.8. Target program has some non-D code - compiled using system GCC (4.8.5) - but the frame in question is D code.

Is there currently any debugger that can show local variables for LDC 1.0.0 on Linux? What is the most reliable one in general (to investigate further)?

I posted an issue on Github for this (https://github.com/ldc-developers/ldc/issues/1651#issuecomment-235930281) and it seems that currently LDC 1.0.0 compiled with LLVM 3.8 does not produce good debugging info.

I've tried to debug DMD generated code with lldbmi2 debugger.
There was a problem with source file / line numbers when stepping, but I fixed it in lldbmi2.
Cannot get variables working - looks like debug information about function context is not compatible with llvm-db
