Segfault in static build when seeking into HTTP input file

Description (last modified by )
For static Linux builds of ffmpeg versions 6.0 and later, a segfault occurs when processing an HTTP input file with a seek (possibly related to range requests or multiple requests against a URL?). For example, when capturing a single frame at 30 seconds as an image from an MP4 URL. If requesting the first frame, or if requesting from an HTTP server which does not support byte-range requests, the segfault does not occur.
I have reproduced this in 6.0.1, 6.1, and git-master, both from source and using builds from https://www.johnvansickle.com/ffmpeg/ but cannot reproduce with 5.1.4. Building from source with a plain ./configure (not including --extra-ldexeflags="-static") does not exhibit the behavior.
Here is a Dockerfile which produces a build from git-master:
FROM debian:bullseye
RUN apt update && apt install -y --no-install-recommends \
autoconf \
automake \
build-essential \
ca-certificates \
cmake \
gdb \
git \
yasm
RUN update-ca-certificates
RUN git clone --depth=1 https://git.ffmpeg.org/ffmpeg.git
RUN cd ffmpeg && \
./configure --extra-ldexeflags="-static" && \
make -j8
And running the resulting container, here is an example command causing the crash:
$ docker run -it --rm ffmpeg-test
root@622d21927980:/# cd ffmpeg
root@622d21927980:/ffmpeg# ./ffmpeg -ss 30 -i http://acrowe.sandbox.frame.io/assets/bbb_1080.mp4 -map 0:v -frames:v 1 -update 1 -y test.jpg
