Control: tags -1 + patch
I had a look at this issue, and tracked it down to
calculateInstructionLengths() trying to the const array
nSwanInstructionLength. With recent compilers and operating
systems, 'const' variables are placed in a read only memory
segment, thus causing this 'bad permission' crash.
The fix is simply to remove the 'const' like this:
diff --git a/rcxlib/RCX_Disasm.cpp b/rcxlib/RCX_Disasm.cpp

I've applied this in debian/patches/writable-swap-inst-len.patch
in git.
