             Bug #: 13130
           Summary: ld does not truncate section names in PE-COFF sections
           Product: binutils
           Version: 2.20
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


Under circumstances unfortunately unknown to me, ld 2.20 can create a PE-COFF
image whose section table contains "long names" (a reference to an item in the
image's string table, instead of an 8-byte name). This is not allowed by the
PE-COFF specification. Quoting the 8th version:

    Executable images do not use a string table and do not support section
names longer than 8 characters. Long names in object files are truncated if
they are emitted to an executable file.

I found out about this behaviour while digging in
libcairo-script-interpreter-2.dll from a 64-bit prebuilt GTK+ bundle
(gtk+-bundle_2.22.1-20101229_win64).

I'm sorry I can't give a more precise bug report. I wouldn't know what linking
flags were used or what objects were fed to ld, because I didn't build the
code.
