Eero Nurkkala requested to merge eenurkka/gstreamer:address-sanitizer-fix into master

With meson configure option: -Db_sanitize=address, the following issue is seen while running the test "tools_gstinspect":

Running suite(s): gst-inspect

=================================================================
==20880==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 51 byte(s) in 9 object(s) allocated from:
    #0 0x7ffb4dbb0b40 in __interceptor_malloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xdeb40)
    #1 0x7ffb4cdf1ab8 in g_malloc (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x51ab8)

SUMMARY: AddressSanitizer: 51 byte(s) leaked in 9 allocation(s).
0%: Checks: 1, Failures: 0, Errors: 1

GOptionEntry man page states that: "Please note that parsed arguments need to be freed separately (see GOptionEntry)." Thus, free the 'min_version' string that has been allocated but never freed.
