Console redirection fails with ECW plugin with MSVC >= 1400

GDAL ticket http://trac.osgeo.org/gdal/ticket/5128 and thread http://lists.osgeo.org/pipermail/gdal-dev/2013-September/037066.html

My recent findings :

Hum, this is an interesting (=annoying) issue. Here's the result of my tests (only on 32 bit builds) :

• release-1600-gdal-1-10-mapserver-6-2 : bad
• release-1600-gdal-1-9-1-mapserver-6-0-3 : bad
• release-1400-gdal-mapserver (latest dev version): bad
• release-1500-gdal-mapserver (latest dev version): bad
• release-1400-gdal-1-8-1-mapserver-6-0-1 : bad
• release-1310-gdal-mapserver (latest dev version): ... good ...
• release-1310-gdal-1-8-1-mapserver-6-0-1 : good

So my conclusion is that it does not depend on the GDAL version, but it does depend on the MSVC compiler. And apparently only MSVC 1310 pleases the ECW SDK. The issue must be a bad interaction between the old ECW SDK 3.3 code and MSVC >= 1400.

@rouault I'm not exactly sure how to reproduce the original issue. may be I should use a specific .tif file? I've tried this but the redirection was working, though the result in the file was truncated. Probably the file buffers are not properly flushed in gdalinfo, but that seems to be an unrelated problem.

I believe I tested it with autotest/gcore/data/byte.tif . The file where gdalinfo output was redirected was always empty. This was with Windows 7 32bit (I believe)

Upgraded to ECW 5.0 SDK (MSVC2008/MSVC2010) hope that's better regarding to this problem

ECW was upgraded, not sure about the status of the issue. Closing for now.
