Executing code

[Ted Williams]

In executing C++ code running on Red Hat Fedora 5 compiled with GNU C++ compiler, I get a SIGSEGV segmentation fault when the code attempts to jump to a data segment holding a small piece of native code.  Is there a way in the C++ code to mark this array of bytes as code?

 

The offending line of code is:

asm ("ljmp *%[src]" : : [src] "m" (Xp));

 

where Xp is a byte pointer to an array in memory holding native code.

 

Thanks for your help!
