RFR(S) 8021296 : [TESTBUG] Test8017498.sh fails to find "gcc" and fails to compile on some Linux releases

[Dean Long]

This looks wrong.  For 32-bit, you probably want REG_EIP, and to change 
the "6" into the correct instruction size for x86.
Or disable the test for 32-bit.  Otherwise the comment:

   43     // Move forward to skip failing instruction

isn't correct and you won't skip the failing instruction.
