I just tried to compile Suse Linux package ctags-2006.5.31-3
with GNU C++ version 4.2 snapshot 20060826.
The compiler said
ruby.c: In function 'parseIdentifier':
ruby.c:227: error: edge from 49 to 51 should not be marked irreducible
ruby.c:227: error: basic block 51 should not be marked irreducible
ruby.c:227: error: edge from 51 to 37 should not be marked irreducible
ruby.c:227: internal compiler error: in verify_loop_structure, at
cfgloop.c:1268
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flag -O3 required.
