this is likely the result of the RELRO enforcement i added last year |
| 15 |
and a corresponding ld.so bug/feature where it tries to set a read-only |
| 16 |
variable after RELRO has made the given area actually read-only (and |
| 17 |
further write/mprotect attempts fail on it). |

all this is the result of the fundamentally broken GNU_STACK 'feature' |
| 20 |
and the best fix is to avoid generating RWE GNU_STACK headers in the |
| 21 |
first place. you'll probably have to dig into the OO build system to |
| 22 |
find out which .so got such a GNU_STACK header and where you can make |
| 23 |
it disappear. |
