Public bug reported:
Multiple memory leaks have been identified in libgdiplus library when
the test code provided ibgdiplus/tests/testgdi.c is compiled with ASAN
enabled. Memory leaks have been found in multiple components of the
library as below :
0x7fce7e31a3d0 in GdipCreatePen1 /home/targets/libgdiplus/src/pen.c:258
0x7fce7e36d4da in GdipCreateSolidFill
/home/targets/libgdiplus/src/solidbrush.c:138
Following is the output of the testgdi.c when it is compiled with ASAN.
