grep G_popen_write */*.c
r.mode/main.c:    reclass = G_popen_write(&reclass_child, "r.reclass", args);
r.rescale.eq/main.c:    fp = G_popen_write(&child, "r.reclass", args);
r.rescale/main.c:    fp = G_popen_write(&child, "r.reclass", args);
r.statistics/run_cmd.c:    fp = G_popen_write(child, argv[0], argv);

The usage of argv and args of G_popen_write() is not the same, desired?

Replying to cwren:

r.reclass.eq gives an error referring to a missing rules file and fails to produce an output.

It's actually r.rescale.eq, not r.reclass.eq.

It hasn't been updated since r.reclass' rules= option became mandatory. r.rescale was fixed with r45358; r.rescale.eq needs the same treatment.

BTW, there's no need to sprintf() the string into a buffer; using a string literal will work.

Done in r54322. The tomorrow's binary snapshot will contain the fix.

Still open.
