            Bug ID: 25029
           Summary: Invalid PE file caused by discarded .rdata section
           Product: binutils
           Version: 2.32
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org

code to reproduce bug

Hello,

I have attached a very simple NASM file that calls the Windows API to display a
message box.
I assemble the file with nasm -f win64 test.asm -o test.o
I then link it with ld -o test_64.exe
-L/c/msys64/mingw64/x86_64-w64-mingw32/lib test_64.o -lkernel32 -luser32

This used to work like a charm with ld 2.30, but produces an invalid file with
ld 2.32. Specifically, the entry point address seems wrong.

I suspect this is because of this commit
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=73af69e74974eaa155eec89867e3ccc77ab39f6d

Since the .rdata section defines output symbols, it is not discarded and the .
= ALIGN(4); instruction causes it to fill with 512 bytes of 0x00. However, this
is not reflected in the resulting PE header
