Hi,
Would it be possible to consider a stable update to gcab 1.2-3 (or its
equivalent as a stable upload)? It fixes a data corruption bug,
#913487; that’s the only change between 1.2-2, which is in Buster, and
1.2-3, which is in Bullseye. The debdiff is as follows:

+ Revert "decomp: fix gcc warning strict-overflow"
+
+ The warning doesn't happen with current build-sys.
+
+ The overlapping behaviour is undefined with memcpy. memmove doesn't
+ have the same semantic either than the loop. Let's revert!

+ Fixes:

+ This reverts commit e48074952743f53d8ac529d4debc421e7e0f6937.
