+# REQUIRES: x86
+
+# Test that the strtab size is included in the allocation even if the
+# strtab itself is empty. To achieve this, we need a number of symbols N
+# where alignTo(N*18, 512) < alignTo(N*18 + 4, 512), where the first
+# positive N fulfilling that is 199.
+
+# RUN: llvm-mc -triple=x86_64-windows-msvc %s -filetype=obj -o %t.obj
+# RUN: lld-link -out:%t.exe -entry:main %t.obj -debug:dwarf
+
+# If the size of the strtab isn't allocated for, llvm-readobj would
+# output SymbolCount: 0 (and dumpbin.exe would error out with "invalid file
+# or disk full, cannot seek to 0x1602").
+
+# RUN: llvm-readobj -file-headers %t.exe | FileCheck %s
+# CHECK: SymbolCount: 199
