Description Francesco 2007-03-22 06:16:52 UTC

Version:            (using KDE Devel)
Compiler:          gcc 3.4.0 
OS:                Linux

This is a companion to bug 126239 but for amd64 instead of x86.  Some C code that exercises the bug is below:

int main() {
  // vex amd64->IR: unhandled instruction bytes: 0x66 0x8D 0x3 0xC9
  asm("lea (%rbx),%ax\n");
}
