It looks like my first guess was wrong. 

Next experiment: Please put a breakpoint on the "for" statement in
ff_img_copy_plane, and set the breakpoint condition to width > dst_wrap.

(gdb) list ff_img_copy_plane
900     }
901
902     void ff_img_copy_plane(uint8_t *dst, int
903                                const uint8_t
904                                int width, in
905     {
906         if((!dst) || (!src))
907             return;
908         for(;height > 0; height--) {
909             memcpy(dst, src, width);
(gdb) break 908
Breakpoint 1 at 0x80bd6eb: file imgconvert.c, line 908.
(gdb) cond 1 width > dst_wrap
(gdb) run -nodropframe -nostats -an hd-test.ts

This breakpoint should trigger before you get the fatal glibc error. Please show
me the output of backtrace command.

(gdb) bt
