xv seems to mess up on some PDS/VICAR files (yes, the voyager 2 pictures) if -O is used; this seems to attack both 2.6.2 and whatever current is (2.6.3?) It seg-faults in the vicinity of the switch in ReadPicFile in xv.c, with a bogus value for the fname (the pointer itself contains some miscellaneous upper-case ascii, if I can trust gdb...) The exact location of the seg fault and other messages that appear differ depending on the number and placement of fprintf(stderr, ...) statements; that is often symptomatic of optimizer bugs. The code itself looks very straightforward in that area. Works fine with -O not specified and doesn't "seem" slower either. -- Pete
