Hi all,
It seems there's a small bug in libevent-trunk (1.5?, 2.0?) when
passing a 'wrong' event_config to event_base_new_with_config.
By 'wrong' I mean a configuration that doesn't make sense, like
avoiding epoll and requiring edge-triggered behavior on linux.
I triggered it with the following sequence (pseudo-code):
config = event_config_new();
event_config_avoid_method(config, "epoll");
event_config_require_features(config, EV_FEATURE_ET);
base = event_base_new_with_config(config); --> Segmentation fault
The following one liner seems to fix it (tested on linux only):
--- event.c 2008-09-26 14:41:13.000000000 +0200
+++ event.c.new 2008-09-26 14:41:21.000000000 +0200
@@ -343,7 +343,7 @@
event_debug(("%s: %d events were still set in base",
__func__, n_deleted));
- if (base->evsel->dealloc != NULL)
+ if (base->evsel && base->evsel->dealloc != NULL)
base->evsel->dealloc(base, base->evbase);
for (i = 0; i < base->nactivequeues; ++i)
hope it helps
malek
