[bug-patch] Patch abort while patching the linux kernel

[Barry Davis]

I'm applying hundreds of patches in a batch, so am using unusual arguments as I want to be able to generate a reject file whilst dry run patching, and have all the rejects from one patch to go to the same file. This has worked fine for ages until I hit this issue with a specific patch file.

The issue occurs when applying the linux-4.4.66 patch to linux-4.4.

I get the same issue using all versions of patch I've tried including v2.5.4 and the latest v2.7.5.

To help you reproduce:

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.4.tar.xz

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/patch-4.4.66.xz

tar xvf opensource/packages/linux-4.4.tar.xz

xzcat patch-4.4.66.xz > patch-4.4.66
