On 32-bit systems, 'string-hash' would raise an out-of-range exception when the second argument was 2^32. * gnu/build/vm.scm (make-iso9660-image): Pass 2^32 - 1 to 'string-hash'. --- gnu/build/vm.scm | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'gnu/build') diff --git a/gnu/build/vm.scm b/gnu/build/vm.scm index f2953621ec..372cf63c68 100644 --- a/gnu/build/vm.scm +++ b/gnu/build/vm.scm @@ -473,8 +473,12 @@ GRUB configuration and OS-DRV as the stuff in it." ;; allows for deterministic builds.
