--- Comment #36 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Created attachment 57854 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57854&action=edit Modified extended test case I modified the extended test case so I could review this and summarize. Currently this is what we get with my comments at the end of each line. I marked some that I think are clearly incorrect. Maybe OK depends on on strictly one chooses to interpret what the standard says. If we assume that one or more spaces is an acceptable separator if followed by a non-value I indicate those with the word space. comma, isreal = F, testinput = ; n= 42 ios= 0 OK, null read point, isreal = F, testinput = ; n= 42 ios= 0 maybe OK comma, isreal = F, testinput = , n= 42 ios= 5010 OK, error point, isreal = F, testinput = , n= 42 ios= 0 OK, null read comma, isreal = F, testinput = . n= 42 ios= 5010 OK, error point, isreal = F, testinput = . n= 42 ios= 5010 OK, error comma, isreal = F, testinput = 5. n= 42 ios= 5010 OK, error point, isreal = F, testinput = 5. n= 42 ios= 5010 OK, error comma, isreal = F, testinput = 5, n= 42 ios= 5010 OK, error point, isreal = F, testinput = 5, n= 5 ios= 0 OK, good read comma, isreal = F, testinput = 5; n= 5 ios= 0 OK, good read point, isreal = F, testinput = 5; n= 5 ios= 0 maybe OK comma, isreal = F, testinput = 7 . n= 7 ios= 0 OK, good read space point, isreal = F, testinput = 7 . n= 7 ios= 0 OK, good read space comma, isreal = F, testinput = 7 , n= 42 ios= 5010 Incorrect point, isreal = F, testinput = 7 , n= 7 ios= 0 OK, good read comma, isreal = F, testinput = 7 ; n= 7 ios= 0 OK, good read space point, isreal = F, testinput = 7 ; n= 7 ios= 0 OK, good read space comma, isreal = T, testinput = 8. r= 42.00 ios= 5010 OK, error point, isreal = T, testinput = 8. r= 8.00 ios= 0 OK, good read comma, isreal = T, testinput = 8, r= 8.00 ios= 0 OK, good read point, isreal = T, testinput = 8, r= 8.00 ios= 0 OK, good read comma, isreal = T, testinput = 8; r= 8.00 ios= 0 OK, good read point, isreal = T, testinput = 8; r= 8.00 ios= 0 maybe OK comma, isreal = T, testinput = 9 . r= 9.00 ios= 0 OK, good read space point, isreal = T, testinput = 9 . r= 9.00 ios= 0 OK, good read space comma, isreal = T, testinput = 9 , r= 9.00 ios= 5010 Incorrect, space? point, isreal = T, testinput = 9 , r= 9.00 ios= 0 OK, good read comma, isreal = T, testinput = 9 ; r= 9.00 ios= 0 OK, good read point, isreal = T, testinput = 9 ; r= 9.00 ios= 0 maybe OK comma, isreal = T, testinput = 3,3. r= 42.00 ios= 5010 OK, error point, isreal = T, testinput = 3.3. r= 42.00 ios= 5010 OK, error comma, isreal = T, testinput = 3,3, r= 42.00 ios= 5010 OK, error comma, isreal = T, testinput = 3,3; r= 3.30 ios= 0 OK, good read point, isreal = T, testinput = 3.3; r= 3.30 ios= 0 maybe OK comma, isreal = T, testinput = 4,4 . r= 4.40 ios= 0 OK, good read space point, isreal = T, testinput = 4.4 . r= 4.40 ios= 0 OK, goor read space comma, isreal = T, testinput = 4,4 , r= 4.40 ios= 5010 Incorrect, space? point, isreal = T, testinput = 4.4 , r= 4.40 ios= 0 OK, good read comma, isreal = T, testinput = 4,4 ; r= 4.40 ios= 0 OK, good read point, isreal = T, testinput = 4.4 ; r= 4.40 ios= 0 OK, good read space I have a followup comment on this.
