dvipdfmx -f test.map test.dvi

を実行すると、dvipdfmxが黙って異常終了して0バイトのtest.pdfができる。

ipam.ttf や ipamp.ttf では正常に動作する。

dvipdfmx -vvvの結果：

これ以上verboseにしても落ちている付近のログは増えない。

私の環境 (macOS, x86_64-darwin) では ipaexm.ttf でも正常終了します。この時の dvipdfmx -vvv のログ：

めぼしい違いは glyph-id が ipaexm.ttf だと小さいことでしょうか…。

glyph-id が ipaexm.ttf だと小さい

でもそれは ipamp.ttf や ipagp.ttf と同じ（それらは Windows でも正常）なので，理由にはならないですね…。

https://gist.github.com/aminophen/bd616ddf70b44768be8def44c8cf766e で対処。
