Hi. Thanks for your report.

It should not happen, of course.

Which platform, which compiler? Is the crash reproducible with
    make check ARGS="-R test_matpoly_u64k1"
?

Does it crash if you run it repeatedly, e.g. with:

    while 
/home/math55/Math/cado-nfs/build/math55/tests/linalg/bwc/test_matpoly_u64k1 ; 
do : ; done

I'd be interested to know if setting OMP_DYNAMIC=true changes something,
e.g. as in:
    
    OMP_DYNAMIC=true make check 
    while OMP_DYNAMIC=true 
/home/math55/Math/cado-nfs/build/math55/tests/linalg/bwc/test_matpoly_u64k1 ; 
do : ; done

(this program has a huge tendency to go bonkers when the CPU is already
quite loaded)
