Bug#635695: libavcodec52: SIGSEGV in ff_imdct_calc_sse() during playback of many wmv files

[Leslie I'Anson]

Hi,

Just to confirm that I am able to reproduce this issue on x86_64 sid
after upgrading libavcodec52 from 4:0.6.2-3 to 4:0.6.2-4.

gdb --args totem ~/downloads/niceday.wmv
Program received signal SIGSEGV, Segmentation fault.

Unsurprisingly, I was unable to determine the version of GGC used
during build (strings -a /usr/lib/libavcodec.so.52 | grep -i GCC).

Best regards,
Leslie
