I am encountering problems on Fedora Core 5, in that lazarus crashes on
displaying some design time forms. The problem seems to be in the
JITForms.pp the code arounf line 920:
CodeTemplate:=MethodAddress('DoNothing');
CodeSize:=100; // !!! what is the real codesize of DoNothing? !!!
GetMem(NewCode,CodeSize);
Move(CodeTemplate^,NewCode^,CodeSize);
creates some new code on the heap, which exec-shield does not like. It
can be fixed as root by:
echo 9 >/proc/sys/kernel/exec-shield
(The default value is 11 on my system) but I was wondering if there was
a better way to fix this. Reading a bit about exec-shield indicated that
executable code on the heap was not portable, so this problem could
appear elsewhere.
