hi, it didn't resolve the crash:

Program received signal SIGSEGV, Segmentation fault.
0x6b72f91d in gst_win32_fsync (wfd=0xffffffff) at gstwin32io.c:278
278       if (G_UNLIKELY (!wfd || wfd->fd == (gpointer) -1))

but if (G_UNLIKELY (!wfd || wfd == (gpointer) -1 || wfd->fd == (gpointer) -1))
yes

in gst_win32_close you are checking wfd == (gpointer) -1, why not in
gst_win32_fsync so.

Well now gst-inspect-0.10 does not crash.

$ gst-inspect-0.10
coreindexers:  memindex: A index that stores entries in memory

Total count: 3 plugins, 16 features

By the way, I am using msys+mingw in a winxp virtualbox client, and host is a
linux. gstreamer checkout is on the host and the dir is shared to the client.
Maybe it can explain this particular case that caused this crash.
