I've run an initial test of this on our build/application and the debugger is working *way* better now. So far no immediate issues - I'll continue testing. Thanks so much for finding, fixing, and sending this along.

FYI, my target:
	- kernel: v4.9.30-rt20
	- GDB/gdbserver: v7.11.1
	- GLibC: v2.25

Regards,

PS: Mathias, my runs of your gdb-issue test utility also appear to run fine.
