If you upload a file via POST as "multipart/form-data" to a C++ program
compiled with libcgicc3, the transmitted file length is 2 bytes too short.

I have attached two files that can be used to reproduce the problem. The C++
file must be compiled with 'g++ test_file_upload_post_cgicc.cpp -lcgicc'. With
the attached perl test file you can trigger the problem. Then evaluate the
output of the debug.* files and compare it with the file that was uploaded. In
the Perl test this is 4bytes large.

With best regards




(Note: upload size limit is set to 16384 kB, after insertion of the required escape characters.)
