In proc mi_expect_stop there's a proc argument reason that's handled like so: ... set r "reason=\"$reason\"," ... That's fine for say: ... set reason "foo" ... for which this evaluates to: ... set r "reason=\"foo\"," ... But there are more complex uses, for instance: ... set reason "breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal" ... which evaluates to: ... set r "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\"" ... Note how in this reason argument, the first two '\"' seems to form a pair surrounding ',disp=', which is not the case, which is confusing. Fix this by only adding the quotes in mi_expect_stop if the string doesn't already contain quotes, such that we have the more readable: ... set reason "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\"" ... Tested on x86_64-linux.
