I can confirm this on the mainline (20030628) with the c++ and c frontends.
With the FORTRAN frontend I get an error:
[omni:~/src/gccPRs] pinskia% g77 pr11361.f
eval.c:30: error: #-lines for entering and leaving files don't match
Here is the backtrace for the c frontend (looks like pfile->map is not being initialized):

Per, this was introduced by your line-map.c change of a few months ago.
line-map.c used to guarantee to retain internal consistency even if
the client gave it nonsense, and cpplib relies on that. After your
patch, it no longer maintains internal consistency.
