5fix adjusting startPage
6
7startPage is adjusted unconditionally for all executables.
8This results in incorrect addresses assigned to INTERP and LOAD
9program headers, which breaks patched executable.
10
11Adjusting startPage variable only when startOffset > startPage
12should fix this.
13
14This change is related to the issue NixOS#10
