   Package: src:austin   
   Version: 3.7.0-8   
   Severity: serious   
   Tags: ftbfs forky sid   
      
   Dear maintainer:   
      
   During a rebuild of all packages in unstable, this package failed to build.   
      
   Below you will find the last part of the build log (probably the most   
   relevant part, but not necessarily). If required, the full build log   
   is available here:   
      
   https://people.debian.org/~sanvila/build-logs/202602/   
      
   About the archive rebuild: The build was made on virtual machines from AWS,   
   using sbuild and a reduced chroot with only build-essential packages.   
      
   If you cannot reproduce the bug please contact me privately, as I   
   am willing to provide ssh access to a virtual machine where the bug is   
   fully reproducible.   
      
   If this is really a bug in one of the build-depends, please use   
   reassign and add an affects on src:austin, so that this is still   
   visible in the BTS web page for this package.   
      
   Thanks.
