--- Comment #9 from gccbugzilla at taggedtype dot net 2009-12-30 15:41 --- I've narrowed it down to this invocation: g++ -o octonion_test.o -c -mxl-compat ld_break.cpp So it's caused by some interaction with -mxl-compat -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42465

--- Comment #7 from gccbugzilla at taggedtype dot net 2009-12-30 15:24 --- Ok, I ran the delta program for a few days and got this message: Died at /home/s.somani/thirdparty/delta-2006.08.03/delta line 123, <> line 64641 Doh! I'll try and see if I can get another test case. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42465

I just want to know if it is guaranteed to finish at some point. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42465

It seems to be related to the use of long double. Does that make any sense? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42465
