I had this happen to me also. This is a known bug that was in (I believe)
112m0.  There are two temporary fixes:

  1: replace all fseek(fp,x,SEEK_CUR) with fseek(fp,ftell(fp)+x,SEEK_SET)
  2: replace the fseek.o from libc.a with one from a previous version.  

1.12m2 definitely does not have this problem.
