Hi, for the render_expired.c program (;-) ).. maximum zoom values all equal 18 and are hardcoded this namely also concerns the twopow[18] array
thus the following macros give a segfault if all values 18 are replaced by something > 18 ; but it works ok for values <= 18 (tested with 16) #define TILE_REQUESTED(z,x,y) \ (tile_requested[z][((x)*twopow[z]+(y))/(8*sizeof(int))]>>(((x)*twopow[z]+(y))%(8*sizeof(int))))&0x01 #define SET_TILE_REQUESTED(z,x,y) \ tile_requested[z][((x)*twopow[z]+(y))/(8*sizeof(int))] |= (0x01 << (((x)*twopow[z]+(y))%(8*sizeof(int)))); this expression : tile_requested[z][((x)*twopow[z]+(y))/(8*sizeof(int))] alone has been tested to be enough to trigger a segfault when function pipe's parameter z=30-3=27 I apologize to not be able to dig further... can someone help remove the segfault if all 18 values are replaced by MAX_ZOOM (<=define included from render_config.h) and MAZ_ZOOM is different from 18 ? Thanks so much in advance !!
