I don't have any experience in using ODBC in GDAL. Let's hope someone else with that experience sees this.<br>
Send all the lines from the strace output. Meanwhile, see if you can work on Windows. It may be an issue in unixODBC.<div><div></div><div class="h5"><br><br><div class="gmail_quote">On Fri, Feb 5, 2010 at 3:30 AM, Gregor at HostGIS <span dir="ltr"><<a href="mailto:gregor@hostgis.com" target="_blank">gregor@hostgis.com</a>></span> wrote:<br>

I have upgraded to 1.7.0 and now get a different error:<div><br>
<br>
$ ogrinfo ODBC:gregor/mosheh@testPgSQL table<br></div>
ERROR 2: CPLMalloc(): Out of memory allocating 4294967297 bytes.<br>
<br>
Yowch, 4 GB seems a bit steep. The PostgreSQL table itself is 5 rows, all points. Why would it want that much? I did try upping the RAM on the server, but I still get "Segmentation fault" The last few lines of strace output are:<br>
<br>
sendto(3, "Qselect ta.attname, ia.attnum fr"..., 275, MSG_NOSIGNAL, NULL, 0) = 275<br>
recvfrom(3, "Pblank\0T\0\2attname\0\0\0\0\23\0@\377\377\377\377attn"..., 4096, 0, NULL, NULL) = 69<br>
mmap(NULL, 4294971392, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ae075e57000<br>
--- SIGSEGV (Segmentation fault) @ 0 (0) ---<br>
<br>
Any ideas?<div><div></div><div><br>
