1.5.19-4: BUG: Using tellg() skips characters on files with DOS line endings

["Yuriy Solodkyy" <solodon at mail dot com>]

Hi,

I've got the following bug that only reproduces itself under Cygwin environment. Using basic_istream::tellg() on files with DOS line endings results in skipping characters from the input. Attached program tellg-bug.cpp tries to reproduce the behavior using a test file test.txt. Commenting out call to tellg() results in correct reading of characters while presence of call to tellg() results in skipping a number of characters that is equal to the number of lines (line endings) in the file. NOTE: File test.txt must have DOS line endings for the bug to be reproducible so please make sure these line endings were not changed while sent over the internet. Converting file to UNIX format with dos2unix utility effectively removes the bug.

I think this bug may be related to the following discussions on the Internet:
