Cause The sdt_misc.exp test did not take into account that some of code in sdt_types.c was conditionally compiled, changing the number of probe points available in the code. Consequence The sdt_misc.exp test would fail on 32-bit and 64-bit x86 architectures because the number of probe points available would not match the expected value. Fix The sdt_misc.exp test takes into account the conditionally compiled code in sdt_types.c when checking for the correct number of probes points. Result The sdt_misc.exp test now passes on 32-bit and 64-bit x86 architectures.
