Thank you for the report. And the analysis :) I tried to fix the problem in Git branch dev_fix_kernel_master by using the do_div() function provided by the Linux kernel instead of the C operator '/': https://github.com/didier-barvaux/rohc/commits/dev_fix_kernel_master Does it fix the problem? I only build-tested it on x86_64 and with an ARM cross-compiler : $ arm-softfloat-linux-gnueabi-gcc --version arm-softfloat-linux-gnueabi-gcc (Gentoo 6.1.0) 6.1.0 Copyright (C) 2016 Free Software Foundation, Inc.
