Backtrace stopped: previous frame inner to this frame (corrupt stack?) (gdb) frame 4

(gdb)?p current Undefined command: "". Try "help". (gdb) p current $1 = 0

The corresponding code exception part is as follows:

bool SrsHlsMuxer::is_segment_absolutely_overflow() { // @see https://github.com/ossrs/srs/issues/151#issuecomment-83553950 srs_assert(current);

// to prevent very small segment.
if (current->duration() < 2 * SRS_HLS_SEGMENT_MIN_DURATION) {
    return false;
}

// use N% deviation, to smoother.
srs_utime_t deviation = hls_ts_floor? SRS_HLS_FLOOR_REAP_PERCENT * deviation_ts * hls_fragment : 0;
return current->duration() >= hls_aof_ratio * hls_fragment + deviation;

}

current' is 0, causing an exception, but I don't understand why the exception occurs.

Duplicated to #3773 and fixed in SRS 5. Please upgrade to SRS 5.0.

ztt19851213 commented 10 months ago

I have looked at the 3773 issue, the phenomenon is the same, but when I look at the srs log and my code, the publish stream has been going on for several minutes, and there has been no reload srs operation, the log shows everything is normal, yet it just crashed.
