[x264-devel] multiple execution?

[karthik]

Hi all

1)     i am pasting a gdb snapshot of x264's execution. 

2)
a)      Can anyone explain the multiple execution of lines 1082,1087 etc.
( I have added 'etc' above because there are many places this happens.. muxers.c...)

The snap also contains `info threads`. which shows 1 thread only

* 1 Thread 1074147968 (LWP 4754)  Encode (param=0xbfffee60, opt=0xbfffee40) at x264.c:1087

3)     These lines are not inside any loop.
