Bug#971411: libopencv-objdetect4.2: LLVM ERROR: inconsistency; Option 'polly' registered more than once!

[Chris Ruehl]

Package: libopencv-objdetect4.2
Version: 4.2.0+dfsg-6+b4
Severity: important
X-Debbugs-Cc: jack at gtsys.com.hk

Hi,
using bullseye on an arm64 to build a opencv test program for HoG the application
failed with following error message:

: CommandLine Error: Option 'polly' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options

code-triggers the error:
        HOGDescriptor hog;
        hog.winSize = _pos_image_size;
<here>  hog.setSVMDetector(get_svm_detector(svm));
        hog.save(_obj_det_filename);


I checked for this message and found some other projects hit same
problem,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=965310

report is for amd64 builds, this might be duplicate but I want to
raise your attention.

Regards
Chris
