[Gdal-dev] MIF/MID problem

[Todd.Southen at bentley.com]

I've attached some tiny files and have included their contents as text
below.

Here's the output from ogrinfo for these files, if you look at the BLOCK
attribute it is incorrect:

I did a quick test with the MITAB library's test programs (MITAB what
OGR uses to read MIF files) and it worked fine with the following MID
records:

42, 123.45, ""
100, "100.5", "12345678901234567890"
100, "100.5", "12345678901234567890"
100, "100.5", "12345678901234567890"

Can you please provide a test file that reproduces the problem?
