Subject: [PATCH] Remove PROT_EXEC from mprotect
|
|
|
|
It looks like mprotect is used here as part of signal handling.
|
|
There doesn't seems to be a reason to have the area of memory
|
|
marked as executable. In fact, on Fedora 9, this causes MLton
|
|
compiled binaries (including MLton itself) to fail.
