16 | # Regression test for PR15693. A breakpoint with a condition that | |
17 | # calls a function that evaluates false would result in a spurious | |
18 | # *running event sent to the frontend each time the breakpoint is hit | |
19 | # (and the target re-resumed). Like: | |
20 | # | |
21 | # -exec-continue | |
22 | # ^running | |
23 | # *running,thread-id="all" | |
24 | # (gdb) | |
