I agree that calling mprotect is the best fix.

There are two ways to fix this, the easiest way is to pass -allow_stack_execute
through to the linker when we want an executable stack. This is problematic
since we'll not be specifying it on the command line. We can tur

No longer working on this, too much troubles are causing to me to fix Darwin
bugs.

In a way it is already needed for powerpc-darwin.

Currently it is not necessary for powerpc, but Apple may indeed change
this in a future version of powerpc-darwin.

I think this should be done for both PowerPC and x86 targets for Darwin. The
vendor compiler rejects nested functions for both targets presumably because of
this, and so trampolines should enable stack execution for both

Subject: Trampolines fail on i686-apple-darwin because stack is not executable
Clarification - I forgot to mention that the code above (the
ENABLE_EXECUTE_STACK macro) must be added to gcc/config/i386/darwin.h
not to gc

I should note that in Apple's GCC for i686-darwin, they warn about this. I
think they should look into fixing the issue here. Anyways confirmed.

Subject: Trampolines fail on i686-apple-darwin
On closer inspection, the problem is that the stack is non-executable.
Adding the following code (borrowed from gcc/config/netbsd.h) to
darwin.h fixes the problem

Subject: Trampolines fail on i686-apple-darwin
Note the gcc.c-torture/execute/nestfunc-5.c fails also (with a bus
error).
