Package: wine
Version: 0.0.20040716-1.2
Severity: normal
The attached program, when compiled as follows:
i586-mingw32msvc-g++ -Wall -o basic.exe basic.cc -lwsock32
Gives this when run under wine:
Assertion failed: fd_is_valid(0), file basic.cc, line 32
(line 32 is the final assertion).
It has no errors at all when run on a real Windows 98 or Windows 2000 box.
The problem seems to be a sudden disappearance of fd 0 when I closesocket()
an invalid socket, which is extremely disturbing and probably leads to
other hard-to-find bugs in wine.

This looks fixed, probably long ago. Closing.
