What happens when you pass the full query through ogrinfo with the
"-sql" switch:
ogrinfo -ro PG:"user= password= host=127.0.0.1 port=5432

Then, follow along the debugging document (

CONFIG "CPL_DEBUG" "ON"

Ciao Luca, I had earlier documented by usual PostGIS debugging steps at https://mapserver.org/optimization/vector.html#debugging-speed-issues-with-postgis Also, instead of the "-map_debug 3" option with shp2img, try "-all_debug 5" (use "3" if you just want to show the draw speed times) The goal would be to output the exact query that MapServer is trying to execute against your database, and then try running that query at the psql commandline. And, if all else fails, be sure to retry all of this with a build of today's MapServer "main" branch, and try with map2img. -jeff -- Jeff McKenna GatewayGeo: Developers of MS4W, MapServer Consulting and Training co-founder of FOSS4G http://gatewaygeo.com/ On 2022-04-01 9:22 a.m., Luca Delucchi wrote: Hi all, I'm getting "Floating point exception" error running shp2img, also running with the debug option I don't get any other information.

Daniel, any chance you can create a ticket for that with a mapfile and sample data that reproduces it ? the png vs. jpeg should not intervene as at the point the error is occuring the code path has been nearly identical (i.e. no png or jpeg library calls have been made yet). thomas On Mon, Mar 21, 2011 at 14:47, Daniel Degasperi wrote: > Hi, > I'v encountered following problem with outputformat png (agg driver): > > shp2img -m /data/sites/R3-MTB-Public/sito/etc/goldart/mtb.map -l "ropeway" > -e 667072.437052 5153904.693426 677867.431220 5164699.687594 -s 1224 1224 -o > test-mtb.png -all_debug 1 (i got a FPE) > > The debugger backtrace gives me: > > Program received signal SIGFPE, Arithmetic exception. > 0x004ba89e in > mapserver::line_image_pattern >>::pixel (this=0x7fffc940, p=0x7fffc43c, x=82, y=-757) > at renderers/agg/include/agg_renderer_outline_image.h:173 > 173 m_filter->pixel_high_res(m_buf.rows(), > (gdb) bt > #0 0x004ba89e in > mapserver::line_image_pattern >>::pixel (this=0x7fffc940, p=0x7fffc43c, x=82, y=-757) > at renderers/agg/include/agg_renderer_outline_image.h:173 > #1 0x004ba8fb in > mapserver::renderer_outline_image mapserver::order_bgra>, mapserv_row_ptr_cache, int> >, > mapserver::line_image_pattern >> >::pixel (this=0x7fffc9e0, p=0x7fffc43c, x=82, y=-757) > at renderers/agg/include/agg_renderer_outline_image.h:860 > #2 0x004bafba in > mapserver::line_interpolator_image mapserver::order_bgra>, mapserv_row_ptr_cache, int> >, > mapserver::line_image_pattern >> > >::step_hor (this=0x7fffc1c0) > at renderers/agg/include/agg_renderer_outline_image.h:668 > #3 0x004bb27f in > mapserver::renderer_outline_image mapserver::order_bgra>, mapserv_row_ptr_cache, int> >, > mapserver::line_image_pattern >> >::line3_no_clip (this=0x7fffc9e0, lp=..., sx=105681, sy=155778, > ex=101946, ey=147898) > at renderers/agg/include/agg_renderer_outline_image.h:931 > #4 0x004c99f9 in > mapserver::renderer_outline_image mapserver::order_bgra>, mapserv_row_ptr_cache, int> >, > mapserver::line_image_pattern >> >::line3 (this=0x7fffc9e0, lp=..., sx=105681, sy=155778, ex=101946, > ey=147898) > at renderers/agg/include/agg_renderer_outline_image.h:992 > #5 0x004cc5b9 in > mapserver::rasterizer_outline_aa mapserver::order_bgra>, mapserv_row_ptr_cache, int> >, > mapserver::line_image_pattern >> >, mapserver::line_coord_sat>::render (this=0x7fffc9a0, > close_polygon=false) at > renderers/agg/include/agg_rasterizer_outline_aa.h:540 > #6 0x004cc9b5 in > mapserver::rasterizer_outline_aa mapserver::order_bgra>, mapserv_row_ptr_cache, int> >, > mapserver::line_image_pattern >> >, mapserver::line_coord_sat>::add_path ( > this=0x7fffc9a0, vs=..., path_id=0) at > renderers/agg/include/agg_rasterizer_outline_aa.h:177 > #7 0x004cca3f in > AGGMapserverRenderer::renderPathPixmapBGRA (this=0xf74350, > line=..., pattern=...) at mapagg.cpp:392 > #8 0x004cccea in > AGGMapserverRenderer::renderPolylineVectorSymbol mapserver::conv_stroke 8u, 256u> >, mapserver::null_markers> > (this=0xf74350, shape=..., > symbol=..., tilewidth=0, tileheight=5, color=..., backgroundcolor=...) at > mapagg.cpp:370 > #9 0x004a9b21 in msDrawLineSymbolAGG(._98 *, ._105 *, ._39 *, ._91 > *, double) (symbolset=0x822ae0, image=0x937b30, p=0x7fffd310, > style=0x87e230, scalefactor=1.) > at mapagg.cpp:1723 > #10 0x0053d573 in msDrawLineSymbol (symbolset=0x822ae0, > image=0x937b30, p=0x7fffd310, style=0x87e230, > scalefactor=1.) at maprendering.c:488 > #11 0x00485521 in msDrawShape (map=0x822ab0, layer=0x87c820, > shape=0x7fffd310, image=0x937b30, style=0, querymapMode=0) at > mapdraw.c:1962 > #12 0x0047fe20 in msDrawVectorLayer (map=0x822ab0, layer=0x87c820, > image=0x937b30) at mapdraw.c:1032 > #13 0x0047f32e in msDrawLayer (map=0x822ab0, layer=0x87c820, > image=0x937b30) at mapdraw.c:822 > #14 0x0047e1e5 in msDrawMap (map=0x822ab0, querymap=0) at > mapdraw.c:468 > #15 0x00440b32 in main (argc=17, argv=0x7fffd848) at > shp2img.c:292 > > When I switch to outputformat jpeg (agg driver) everything is fine. > > MapServer is 5.6.6 on 64bit CentOS 5.5 > > Best regards, > Daniel > > -- > Daniel Degasperi R3 GIS Srl - GmbH www.r3-gis.com > ___ > mapserver-users mailing list > mapserver-users@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/mapserver-users > ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
