--- Comment #2 from Kip Warner <kip at thevertigo dot com> ---
Hey Jim,

Sorry, there was a typo in my original post. I meant ebreak, not cbreak.

I tried the semihosting trap instruction sequence and I still had the same
result on the ebreak instruction:

    asm volatile("slli x0, x0, 0x1f; ebreak; srai x0, x0, 7");

While folks figure out whether this is a bug in GDB or intentional, do you =
have
a suggested workaround for what I'm trying to achieve? I'm aware of the kil=
l()
and raise() functions, but they require an #include, whereas inline asm rol=
led
into a #define macro does not.
