Summary: Wine preloader segfaults
           Product: Wine
           Version: 20040615
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-loader
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Ever since the wine-preloader was first checked into CVS before 20040615 was
released, it has constantly segfaulted when loaded. If I invoke wine-pthread
manually, windows executables work though.  Today, I did a clean recompile of
WINE with only the CFLAGS "-O2 -pipe" and got the following from GDB:
---

Starting program: /usr/local/bin/wine-preloader

Program received signal SIGSEGV, Segmentation fault.
0x780011d0 in write ()
(gdb)

---

I'm not sure if this helps or makes problems worse, but with my original CFLAGS
of "-O2 -march=athlon -frename-registers -fomit-frame-pointer" I got a different
error message from GDB.  It printed out a memory address followed by open64(),
which I find odd.  Also, when I allow it to dump a core file, and backtrace
that, it says:

---
Program terminated with signal 11, Segmentation fault.
#0  0x7800106e in open64 ()
(gdb)
---

I hope the information I've provided is useful.
