[Qemu-devel] [PATCH 09/29] hw/sparc/leon3.c: Fix memory leak spotted by valgrind

[Shannon Zhao]

From: Shannon Zhao <address@hidden>

valgrind complains about:
==21199== 2,468 (128 direct, 2,340 indirect) bytes in 1 blocks are definitely 
lost in loss record 1,094 of 1,125
==21199==    at 0x4C2845D: malloc (in 
/usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
