Segfault in 7.1 with BUILD_AZURE_BACKUP turned on, need help to troubleshoot further

Hello,

I built a version of foundationdb 7.1 branch to enable backup to Azure blobstore. I took the latest in the 7.1 branch and followed steps outlined [here](https://github.com/FoundationDB/fdb-build-support)

Upon running fdbbackup, it segfaults. However, I am unable to obtain a meaningful location/trace. Looking for advice on how I should get more troubleshooting details.

NOTE: I replaced the binaries on top of a 7.12 release that was installed via dpkg. I am also looking for instructions to build a package from the compiled output (instead of copying over the binaries).

It was built with the following `cmake` options.

$ cmake -DNDEBUG=0 -DBUILD_AZURE_BACKUP=ON -S src/foundationdb -B build_output -G Ninja

// binaries installed and foundationdb restarted
// set sample data via fdbcli - db seems to work for trivial queries (no extensive testing done)

$ export AZURE_KEY= xxxxxxxxxxx
$ fdbbackup start --destcontainer "azure://............./fdbtest02/testing/" --log

SIGNAL: Segmentation fault (11)
Trace: addr2line -e fdbbackup.debug -p -C -f -i 0x7f7fec5bf420
