g_array_unref assertion failure in ldm_add_fd() function

[diwu1989]

ldmtool version 0.2.4-2

I'm getting a error when scanning a disk:

Unable to determine sector size of merged.flat. Assuming 512 byte sectors

(ldmtool:31287): GLib-CRITICAL **: g_array_unref: assertion 'array' failed
[
]

The gdb backtrace looks like this:

(gdb) where
#0  0x00007ffff72e8afb in g_logv () from /lib/x86_64-linux-gnu/libglib-2.0.so.0

#4  0x00007ffff7db32c0 in ldm_add () from /usr/lib/x86_64-linux-gnu/libldm-1.0.so.0

The full gdebug log looks like this right before the assertion

This is possibly fixed by a856552

Could you try compiling it from git?

It certainly works for me from git, using a pretty new version of glib2.
