            Bug ID: 50622
           Summary: wldap32 calls Linux libraries with wrong conventions
           Product: Wine
           Version: 6.0-rc6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wldap32
          Assignee: wine-bugs at winehq.org
          Reporter: gmascellani at codeweavers.com
      Distribution: ---

The code generated by dlls/wldap32/ber.c calls liblber with wrong calling
conventions. For example, looking at the object disassembly I see stuff like:

   1d5bf:       48 8d 54 24 26          lea    0x26(%rsp),%rdx
   1d5c4:       48 89 d9                mov    %rbx,%rcx
   1d5c7:       e8 e4 9c ff ff          callq  172b0 <ber_printf at plt>

Clearly it is trying to call the Linux ber_printf with Microsoft calling
conventions (while liblber expects SYSV calling conventions, using RDI, RSI and
such). This causes adsldp tests to fail on my computer, in a 64-only Wine
build:

../../../../libraries/liblber/encode.c:513: ber_printf: asserzione "LBER_VALID(
ber )" non riuscita.
