I have an X11 client, that, until recently, worked just fine. However, during the past month, it has taken to dumping core when trying to display data. I can run the program 10 times, and it'll fail about 80% of the time. sometimes specifying different amounts of data (both more and less) gets around the problem. using adb on the core points to a routine that appears to be fine. I tried using the debugging version of malloc(), and calling malloc_verify in the offending routine. I get malloc_verify: bad block size (52232960) at 0x7a904 those numbers tend to be fairly reproducible for a given date file. unfortunately, I don't know what to do now. Can anyone give me any suggestions as to how to track this down? the only change we've made lately is to move our 50s to 8M, but this problem also happens on my 3/280, which hasn't been upgraded. SunOs 3.5, X11R3 fixes 1-10, gcc 1.34 happens on 3/50, 3/110, 3/280.
