build/browse_py.h contains, in its entirety:

const char kBrowsePy[] =
;

... which looks wrong.

[Comment 2 Stuart Shelton 2017-10-10 20:16:49 UTC]

Running:

"./src/inline.sh" kBrowsePy < ./src/browse.py

... manually produces reasonable-looking output.  What's going on here?

[Comment 3 Fabian Groffen 2017-11-12 12:56:10 UTC]

this is because od dies with Illegal instruction (e.g. coreutils needs a fix)

[Comment 4 Fabian Groffen 2017-11-12 13:05:11 UTC]

updating coreutils to 8.28 includes a fix.
