[Bug target/25255] packed structure: pointers to self result in "error: initializer for integer value is too complicated"
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=25255 Jeffrey A. Law changed: What|Removed |Added Status|NEW |RESOLVED CC||law at redhat dot com Resolution|--- |FIXED --- Comment #5 from Jeffrey A. Law --- The H8/300 variant of this bug was specific to the COFF support which was removed in gcc-4.5. Generic ELF support provides the necessary #defines to avoid this problem. I've been unable to configure gcc-4.5 for the openbsd-4.5 in the manner suggested by Rob: *** Configuration x86_64-unknown-openbsd4.5 not supported My best guess is there was some local configury bits in Rob's build. Marking as resolved. Rob, if you want the openbsd issue looked at further, please open a new bug.

--- Comment #4 from rob1weld at aol dot com 2009-03-30 23:35 --- I ran into this Bug on the Trunk for Platform x64_86-unknown-openbsd4.5 . I tried the test "C" code from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25255#c1 and got this: /home/user/gcc_build/test_gcc_2.c:18: error: initializer for integer/fixed-point value is too complicated /home/user/gcc_build/test_gcc_2.c:18: error: initializer for integer/fixed-point value is too complicated This error does not occur with gcc version 3.3.5 on: # uname -a OpenBSD openbsd.localdomain 4.5 GENERIC#5 amd64 # gcc/xgcc -v Using built-in specs.
