bug#65441: leptonica 1.83.1 ioformats_reg test failure

[Ahmad Draidi via Bug reports for GNU Guix]

Greetings,

I looked into this and can see that running tests in parallel causes
random failures. I've seen the same thing on Debian also.

I've sent in a patch series[1] that includes a fix for this.

Thanks,
Ahmad
