Summary	02825: crossbow: Crash on "Crossing Bridge" stage
Description	This is an odd one. In testing It doesn't happen all the time. Artwork, NVRAM doesn't seem to matter. I was able to get a save state in which it crashes nearly 100% of the time for me under certain conditions as detailed below
Steps To Reproduce	Play and choose the Red Path each time. On the third Red choice, you will goto the "Crossing Bridge" stage. All you need to do to trigger the bug is shoot the rock that comes from the right hand side of the screen and across the bridge. or Load with the save state provided as attachment: mame crossbow -state 9 - Choose the RED path - Play the stage as mentioned above, only shooting the Rock. The crash will happen very shortly afterwards .
Additional Information	Largely redundant backtrace here: Program received signal SIGSEGV, Segmentation fault. 0x0053c5d4 in draw_sprites (screen=0x9771f6c, bitmap=0x12ac1fe0, cliprect=0x22fc1c, scroll_offset=0, check_collision=1) at src/mame/video/exidy440.c:372 372 pen = left \| old[0]; (gdb) bt #0 0x0053c5d4 in draw_sprites (screen=0x9771f6c, bitmap=0x12ac1fe0, cliprect=0x22fc1c, scroll_offset=0, check_collision=1) at src/mame/video/exidy440.c:372 #1 0x0053c5d4 in draw_sprites (screen=0x9771f6c, bitmap=0x12ac1fe0, cliprect=0x22fc1c, scroll_offset=0, check_collision=1) at src/mame/video/exidy440.c:372 #2 0x0053c5d4 in draw_sprites (screen=0x9771f6c, bitmap=0x12ac1fe0, cliprect=0x22fc1c, scroll_offset=11092533, check_collision=1652541860) at src/mame/video/exidy440.c:372 #3 0x0053c5d4 in draw_sprites (screen=0x9771f6c, bitmap=0x26, cliprect=0x22fc60, scroll_offset=2303392, check_collision=0) at src/mame/video/exidy440.c:372 #4 0x0053c5d4 in draw_sprites (screen=0x10e81750, bitmap=0x19, cliprect=0x0, scroll_offset=218526247, check_collision=-697570048) at src/mame/video/exidy440.c:372 #5 0x0053c5d4 in draw_sprites (screen=0x10e81750, bitmap=0x2019, cliprect=0x0, scroll_offset=10901698, check_collision=283645776) at src/mame/video/exidy440.c:372 #6 0x0053c5d4 in draw_sprites (screen=0x10e81750, bitmap=0x2019, cliprect=0x0, scroll_offset=13772436, check_collision=568858448) at src/mame/video/exidy440.c:372 #7 0x0053c5d4 in draw_sprites (screen=0x11751768, bitmap=0x2019, cliprect=0x11751770, scroll_offset=2, check_collision=45) at src/mame/video/exidy440.c:372 #8 0x0053c5d4 in draw_sprites (screen=0x11751768, bitmap=0xc37e, cliprect=0x5163f1cf, scroll_offset=427480, check_collision=0) at src/mame/video/exidy440.c:372 #9 0x0053c5d4 in draw_sprites (screen=0x9751f7c, bitmap=0xba2, cliprect=0x5163f1cf, scroll_offset=427480, check_collision=218526247) at src/mame/video/exidy440.c:372 #10 0x0053c5d4 in draw_sprites (screen=0x9701efc, bitmap=0x0, cliprect=0x0, scroll_offset=0, check_collision=158080928) at src/mame/video/exidy440.c:372 #11 0x0053c5d4 in draw_sprites (screen=0x6911e58, bitmap=0x6901f08, cliprect=0x16fc8b0, scroll_offset=150, check_collision=2086085928) at src/mame/video/exidy440.c:372 #12 0x0053c5d4 in draw_sprites (screen=0x6, bitmap=0x6871fe8, cliprect=0x22cfce0, scroll_offset=2013270425, check_collision=32) at src/mame/video/exidy440.c:372 #13 0x0053c5d4 in draw_sprites (screen=0x6, bitmap=0x6871fe8, cliprect=0x3d, scroll_offset=88, check_collision=2293728) at src/mame/video/exidy440.c:372 #14 0x0053c5d4 in draw_sprites (screen=0x7ffdf000, bitmap=0x0, cliprect=0x22ffb0, scroll_offset=4198987, check_collision=6) at src/mame/video/exidy440.c:372 #15 0x0053c5d4 in draw_sprites (screen=0x1, bitmap=0x9, cliprect=0x22fff0, scroll_offset=2086242773, check_collision=0) at src/mame/video/exidy440.c:372 #16 0x0053c5d4 in draw_sprites (screen=0x0, bitmap=0x0, cliprect=0x7ffdf000, scroll_offset=0, check_collision=2293704) at src/mame/video/exidy440.c:372 #17 0x0053c5d4 in draw_sprites (screen=0x401280, bitmap=0x0, cliprect=0xc8, scroll_offset=256, check_collision=-285217025) at src/mame/video/exidy440.c:372
