## T14: V3 unwind info in a relocatable object file (.obj).
## This tests the relocation-based resolution path where .pdata fields
## are zero and relocations point to the actual symbols.
##
## Uses the same V3 xdata as T2 (single epilog mirroring prolog):
##   .xdata = 030B0823070200181400000006000405 38343C00
##
## .pdata layout (12 bytes, all zeros — resolved via relocations):
##   +0: 00000000  StartAddress  → reloc to func
##   +4: 00000000  EndAddress    → reloc to func (addend 0x20 in SectionData)
##   +8: 00000000  UnwindInfoOffset → reloc to .xdata
