The build path is embedded in /usr/bin/pbyacc:

  
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/aespipe.html

  /build/1st/aespipe-20050907/aespipe.c:181
  vs.
  /build/2/aespipe-20050907/2nd/aespipe.c:181

The attached patch to debian/rules fixes this by adding
-ffile-prefix-map and --debug-prefix-map to CFLAGS.

According to my local tests, with this patch applied aespipe should
build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining aespipe!

live well,

Subject: [PATCH] debian/rules: Pass -ffile-prefix-map and --debug-prefix-map
 via CFLAGS to avoid embedding the build path.
