Rebuild. Good news first: With the updated values, the patgen binary
builds, and AFAICS runs as intended (if run manually from command line).

BUT the test fails again:

$ cd Work/texk/web2c
$ make check
[…]
FAIL: patgen.test

(again with ENOMEM segfault)


JUST to run fine if the test is executed by hand, of course (?):

$ export srcdir=../../../texk/web2c
$ $srcdir/patgen.test
[…]
This is PATGEN, Version 2.4 (TeX Live 2020/dev)
[…]

Outputs of `ulimit` and `env` are identical, except $SHLVL which is 7
for the `make check` run and 2 for manual run.


Whodunnit? `make`?


Bad memories of the texk/web2c/omegafonts issue on powerpc-linux last
april…


Best,
