I confirmed that building through sbuild in a sid chroot behaves exactly
the same way as building on my sid machine.

Control: tag -1 upstream fixed-upstream

The mismatch between 1.3.268 and 1.2.275 is likely the problem.
https://github.com/KhronosGroup/Vulkan-Tools/commit/64d9218726083ece79099341249890c75a5c4491
is where this issue was fixed and that commit is part of 1.3.274 (and higher).

If you downgrade src:vulkan-loader to 1.3.268.0-1 then it should compile again.

Looks like the vulkan-sdk versions need to be in sync.

close 1063370 1.3.275.0+dfsg1-1
thanks

Didn't realize there was a bug filed for the FTBFS.
