/*
 * PCF encoding offset out-of-bounds access
 *
 * The font has 1 metric but an encoding entry that references index 100,
 * far past the metrics array.  Without the fix, this creates a wild
 * pointer that is later dereferenced.
 *
 * With the fix in pcfread.c, encoding offsets are validated against
 * nmetrics.
 *
 * Test font: test/data/encoding/evil-encoding.pcf
 * Generated by: test/gen_evil_pcf_encoding.py
