File gcin-reproducible.patch of Package gcin

Author: Bernhard M. Wiedemann <>

A PIN_JUYIN struct occupies 10 bytes
(from how compilers do alignment and padding)
but the code only writes 9 of them
leading to random bytes in the output file
which makes builds unreproducible
unless ASLR is disabled in the build system

See for why this matters.
