--- Comment #7 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2011-08-24 12:36:57 UTC --- Created attachment 25087 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25087 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 == avr-gcc assert-i.c -S -Os -g -v Using built-in specs.
