[Fontconfig] font memory leak issue

[Archana :)]

Hi,

There is some memory leak issue in my code,Valgrind is showing as

53,200 (19,200 direct, 34,000 indirect) bytes in 50 blocks are definitely
lost in loss record 155 of 158
==11740==    at 0x4025016: realloc (vg_replace_malloc.c:525)

(unixfontconfig.cpp:74)
==11740==    by 0x4B3439C: FontConfig::FindFont(char const*, bool, bool)
(unixfontconfig.cpp:49)

Can anyone suggest me how to resolve this issue.
