GRIB driver crashes with large datasets

Description

When trying to list the information of a large (around 19000 bands) GRIB dataset, gdalinfo crashes. Python bindings crash with a segfault on the same dataset. Similar datasets with a smaller set of bands work fine. A sample large dataset from ECMWF ERA40 reanalysis (around 1.1 Gb) is available for testing in ​here. Running gdalinfo with debug information doesn't yield anything.

I'm afraid that file is too large for Chaitanya or I to practically download.

I could download it (not sure I could find what's wrong...) but the link seems to be broken. Permission problem on the server?

Milestone: → 1.6.1
Resolution: → fixed
Status: new → closed

Ok, file finally downloaded now... In fact this issue has been fixed in trunk and branches/1.6 just a few weeks ago as ticket #2751.

But as this file also produces a lot of info printf on the console, I've removed them in trunk (r16562) and branches/1.6 (r16563)
