Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14. Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla). --ryan. Please re-enter a new bug if you can catch it doing that in the debugger. :) Whoops, I see this was intended to be Chinese. Can you add an english translation of the error? Let's see if I can decode this a little bit... 0xC0000005 usually means a segmentation fault... I imagine that 0x00000000 is a NULL pointer dereference. The code itself looks fine offhand. Are your video drivers up to date? Can you reproduce this with the current SDL snapshot? http://www.libsdl.org/tmp/SDL-1.2.zip If so, do you get the same problem with testgl, included in the test folder in the SDL source archive? Please submit a new bug report if you're still seeing this issue with SDL 1.3. Thanks! |
