Ive given the source and a preprocessed version of the complete file

compiled with
gcc -Wall -O3 -fomit-frame-pointer -Wextra -g
-I/usr/src/kernel/linux-2.6.29.1/include   -c -o file.o file.c

Problem is that adding removing code seems to make the problem
appear/disappear.

I do hope that this is enough, as it seems that the problem is in the 

   i_len2 = fread( ....)
   if( i_len2 < 188)

cant be a much simpler test case
