I can repeat the error with another computer (Vista 32-bit). This time 
the error occurs at scanline 44731 when progress bar had advanced to 
value of 90.
Obviously there is a lack of some resource but I cannot imagine what it is and
how I could give more of it for gdal_translate. Both computers have 2 GB of
memory but resource manager does not show signs about running out of memory.

There is now a 460 MB zip file at
http://latuviitta.org/documents/TiffAppendToStrip_error.zip

It contains the source tiffs and .vrt file "UM52.vrt" and after unzipping it
should be ready for a test with
gdal_translate -of GTiff UM542.vrt output.tif

SRS is EPSG:3067 if it matters.
