We run Clang Static Analyzer (scan-build 7) and found a few interesting spots in the code. Shifting left a negative value is one of them: https://public-artifacts.signalwire.cloud/drone/freeswitch/spandsp/15/report-b3d9e4.html#EndPath There were 9 issues total reported: https://public-artifacts.signalwire.cloud/drone/freeswitch/spandsp/15/index.html @coppice-git May I ask you to take a look at these?
