           Summary: Weird parsing error CS8025: Arg_InsufficientSpace
           Product: Mono: Compilers
           Version: 1.2
          Platform: Other
        OS/Version: Other

Yesterday I updated to revision 88466 of Mono/Mcs-SVN and noticed a strange
behavior of gmcs when compiling my project.

A gmcs-command that ususally worked (with some earlier svn revision, and
definitely works with the official 1.2.5.1-Release) invoked with no special
options (only references, resources, target, out and input files)
always gave me this:

Example1/TTest2/TTest2.cs(1584,31): error CS8025: Parsing error

and aborted.

With rev. 88583 I still get the same behaviour.

The weird thing about it is, that the parsing error goes away if I make an
(almost random) change to the Sourcefile TTest2.cs. E.g. an extra NewLine
somewhere in the code or even a singe letter added to some comment makes the
error go away.

Invoking the same gmcs-command with the -v option leads to the stacktrace given
below. I hope it won't be necessary to provide the file causing the error
itself, because it is deeply nested within my project and every change makes
the error go away.

If it helps in any way, here's the output of "file TTest2.cs"
TTest2.cs: ISO-8859 C++ program text, with very long lines, with CRLF line
terminators
