False reports under SetEnvironmentVariable

As of r57 , the following code:
===test.c===
#include

int main(void) {
SetEnvironmentVariableA("FOO", "foo");
return 0;
}
#

(compiled with "cl /Zi /MTd")
gives one report:
Error `#1`: UNADDRESSABLE ACCESS: writing 0x000117e8-0x000117e9 1 byte(s) within 0x000117e8-0x000117ec
