something fishy with Git commit and log from file

The following command fails on my repository:

    $ git commit --file=clog
    fatal: could not read log file 'clog': No such file or directory

    $ cat clog
    toto

Using the following command the commit pass without problem:

    $ cat clog | git commit --file=-

With GDB I get:

$ gdb --args git ci --file=clog This GDB was configured as "i686-pc-cygwin"... (gdb) break strbuf_read_file Breakpoint 1 at 0x44e64a: file strbuf.c, line 301. (gdb) run Starting program: /usr/local/bin/git.exe ci --file=clog

Breakpoint 1, strbuf_read_file (sb=0x22cac0, path=0x22ccfa "clog", hint=0) at strbuf.c:301 301 fd = open(path, O_RDONLY); (gdb) print path $1 = 0x0

???? outch, this is strange, or a gdb artifact?

(gdb) n 302 if (fd < 0) (gdb) print fd $2 = -1 (gdb) print *0x22ccfa $3 = 1735355491 (gdb) print (char)*0x22ccfa $4 = 99 'c' (gdb) print (char)*0x22ccfb $5 = 108 'l' (gdb) print (char)*0x22ccfc $6 = 111 'o' (gdb) print (char)*0x22ccfd $7 = 103 'g' (gdb) print (char)*0x22ccfe $8 = 0 '\0'

But looks like path really contains 'clog'!!!

No luck for now to find the problem. Note that the same command pass fine on other repositories. At this point this looks really like some kind of memory corruption...

I'm on Windows, using Git for Cygwin and the compiler is:

$ gcc --version gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

Pascal.
