[asan] Fix memory leak in gethost.c #81

Closed gregorynisbet-google closed 8 months ago

gregorynisbet-google commented 8 months ago

Fix a harmless memory leak in gethost.c. This enables tcsh as a whole to compile with ASAN enabled.

The invocation below will fail without this patch.

$ ./configure CFLAGS=' -g -fsanitize=address ' LDFLAGS=' -fsanitize=address ' && make
