[PATCH] libelf: Free phdr on notcvt malloc failure in getphdr_wrlock

[Mark Wielaard]

Make sure that on all error paths the pre-allocated phdr is freed and
set to NULL. The notcvt malloc failure path was missed.

        * libelf/elf32_getphdr.c (getphdr_wrlock): Free state.phdr and
        set it to NULL on notcvt malloc failure.
