ltrace is supposed to be an strace equivalent, except it should show
functions called instead of syscalls.
Running it on my i386 system (Atom N270, running linux-vanilla 4.4.8,
alpine edge, a few days out of date), it apparently no longer picks up any
$ echo "foo" |ltrace /bin/cat
+++ exited (status 0) +++
cat is busybox cat (shared/stripped).
Looking at the log, the differences I see are:
-at one point, the upstream source was redirected, and had a new checksum
-it was rebuilt
-a linux-headers dependency was added
Any ideas what's going on here?
