[x264-devel] [BUG] Out of range runtime error in x264_weights_analyze method

[Sasi Inguva]

Hi,

We found a test file where x264 encoder crashes with runtime error like this
 ./x264 --input-res 1024x640   -o ./tmp.x264  ./concat_bug_video.yuv
yuv [info]: 1024x640p 0:0 @ 25/1 fps (cfr)
x264 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX
x264 [info]: profile High, level 3.1
encoder/slicetype.c:407:97: runtime error: value inf is outside the range
of representable values of type 'int'

This is our compilation configuration -
make clean && ./configure  --enable-pic --enable-static
--extra-cflags="-fsanitize=return,returns-nonnull-attribute,vla-bound,unreachable,float-cast-overflow
-fno-sanitize-recover=all"
--extra-ldflags="-fsanitize=return,returns-nonnull-attribute,vla-bound,unreachable,float-cast-overflow
-fno-sanitize-recover=all" && make -j12

Here is the public downloadable link for the test file

Let me know if anymore information is needed.  Thanks
