fortify-headers adds a UD2 instruction because the compiler cannot
|
|
determine the size of "spjump_start" that is used with memmove
|
|
in the remap_spjump() function of pmcl-kernel.c. Disabling this
|
|
allows CCL to run without encountering an "Illegal instruction".
|
|
|
|
Use -no-pie to suppress compiler warnings about "relocation in
|
|
read-only section `.text'" and "creating DT_TEXTREL in a PIE".
