I can replicate the crash with the JP2ECW driver with ECW SDK 3.3. It occurs 
actually in the SDK itself, not in GDAL, so nothing that we can really do 
about that (except using GDAL API Proxy, see below). Newer versions of the SDK 
don't produce this crash.

Frank's above suggestions are the way to go. Tamas' builds do include MrSID 
support as a plugin (XXXX-mrsid.msi packages). But they also include the 
OpenJPEG driver, which can successfully open this file and should be the next 
driver used after skipping JP2ECW :

$ gdalinfo --config GDAL_SKIP JP2ECW

If you want to use the JP2MrSID driver, you need to set --config GDAL_SKIP 
"JP2ECW JPEG2000 JP2OPENJPEG"

Indeed, 

$ gdalinfo  --config GDAL_API_PROXY YES 
IMG_PHR1A_MS_201202250025599_SEN_PRG_FC_5847-002_R1C1.JP2
ERROR 1: Read from pipe failed
gdalinfo failed - unable to open

But that's only band-aid and you need to use another driver in order to open 
the file successfully
