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
Reporter: florin.saft...@soft-to-you.com
Target Milestone: ---

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
