Subject: GNU patch out of bounds read, null pointer crash and double free

The recent release of GNU patch 2.7.6 fixed an old out of bounds read I
had reported in 2015:

out of bounds read with malformed patch in pch_write_line


I re-checked patch now and found a few more issues:

segfault / null pointer (probably crash only)

double free in function another_hunk()
