FW: Re: [Libjit-developers] sigsegv while running tutorial program

[ktreichel]

 Hi Ravi,

yes this segfault is a known issue with libjit 0.0.6 on RedHat or Fedors 
because memory allocated with malloc is not executable on these systems.
Thie issue is fixed in the CVS version and you should use the cvs version 
because a lot in libjit is changed since the last release.
