It should be a bug in event parser. I guess the patch below will fix it:
diff --git a/tools/perf/util/parse-events.l b/tools/perf/util/parse-events.l index 488362e14133..aafca33a8a09 100644 --- a/tools/perf/util/parse-events.l +++ b/tools/perf/util/parse-events.l @@ -76,7 +76,7 @@ num_hex 0x[a-fA-F0-9]+ num_raw_hex [a-fA-F0-9]+ name [a-zA-Z_*?][a-zA-Z0-9_*?]* modifier_event [ukhpGH]{1,8} -modifier_bp [rwx] +modifier_bp [rwx]+ %%
