Hey Andrew, It looks like the user times displayed by exec are messed up. Check out the one below (this was done on Solaris 9 it it makes a difference). Btw., I think we might want to format large time values as "m:ss" (or "h:mm:ss" if they're over an hour long) instead of "s.uuu". In any case, the value shouldn't exceed the width of the field. $ time ./27_stringbuf_virtuals >/dev/null && ./run ./27_stringbuf_virtuals real 0m4.139s user 0m4.130s sys 0m0.010s NAME STATUS USER SYS ASSERTS FAILED PERCNT 27_stringbuf_virtuals 0 86128.110 0.020 Martin
