assert-i.c

Set to REOPENED: This bug is still not dead; I see it with r178035 from trunk
for the attached, precompiled file from avr-libc.

There are similar PRs PR49994, PR49879 which all are fixed. I chose to reopen
this one because it occurs for the same target and similar message.

== Command line ==
