SDCC 4.7.0 Release
It's not on my list of my personal priorities for SDCC 4.7.0 at https://sourceforge.net/p/sdcc/wiki/Philipp%27s%20TODO%20list/ ; I'm aiming mostly for stability improvements / bugfixes, not new features, and just about 0.5 years of development instead of the about 1.5 we used for 4.6.0. But I don't know what other SDCC devs will work on. Last time this was discussed, it looked like @janko-5 might do it, possibly with some help from me, but I haven't heard from him in a while.
Which version of SDCC, used with which command-line options? Do you have a small compileable code sample to reproduce this?
