Has anyone used GDB for remote debugging? I have implemented
a gdb stub in an embedded target, gone to lengths to support
breakpoint commands and multithread-support commands, just to
discover that gdb (including 5.2.1) behaves not only like a
fscking moron, but *non-deterministic* on top of that.

In short: when my target hits a breakpoint, gdb removes the
breakpoint, but keeps it marked as "keep" in "info breakpoints".
Setting a thread-specific breakpoint with "thread apply..."
usually, but not always, results in gdb not sending any breakpoint
command at all. Then again, setting new breakpoints sometimes
results in gdb (correctly) re-setting the original breakpoint
that caused the target to stop. Gdb seems confused when used
with a remote target. Very confused. Does anyone recognize this
problem?
