[RFH] c-blosc2 segfaults on mips64el

[Antonio Valentino]

Dear all,
starting from the last update of c-blosc2 to v2.15.2 the package started 
to fail tests on mips64el: segfault for 5 tests of the unit test suite

The following tests FAILED:
317 - test_get_slice_nchunks (SEGFAULT)
726 - test_nthreads (SEGFAULT)
733 - test_set_slice_buffer (SEGFAULT)
735 - test_sframe_lazychunk (SEGFAULT)
871 - test_update_chunk (SEGFAULT)

see also [1]

I have reported the issue upstream [2] but c-blosc2 developers do not 
have access to a mips64el machine to track down the issue.

I have also requested for access to one of the porterboxes to track down 
the issue myself.

Unfortunately I was not able to reproduce the issue because the package 
builds successfully and passes all tests on eberlin.debian.org (mips64el).

I would kindly ask for an advice about how to proceed.
