Description Eugene A. Strizhov 2009-07-21 16:43:12 UTC 
I've tried to compile source where `enum' in constructor is presense and used inside. This combination issues internal error. Sample source file is attached, command line is:
  g++ -flto -c err-lto-lso-l821.c

  g++ -v:
Using built-in specs.

Comment 4 Richard Biener 2009-10-18 12:57:27 UTC 
Is this still a problem on arm?
Comment 5 Eugene A. Strizhov 2009-10-23 07:51:48 UTC 
I've rechecked it with lto merged with rev. 152279 and there is no effect any more.
Comment 6 Richard Biener 2009-12-11 16:47:14 UTC 
Fixed thus.
