--- Comment #2 from Launchpad <feedback at launchpad dot net> 2011-08-20 19:04:30 UTC ---
jas mann added the following comment to Launchpad bug report 827806:
Sorry, I don't know, but I can venture some guesses:
Q. Why did I code in such a manner as to foil parsing of the source?
A. Careless, or worse? The error was obvious of course so in that respect a
crash was as good as a diagnostic.
Q. You want the preprocessor output?
A. It's gone. I thought perhaps the bug reporting script grabbed it.
Q. Why didn't I attach the preprocessor output to the bug report?
A. I guess it wasn't immediately obvious how, and I was in a rush.
Q: What was the code that caused the problem?
A. I don't remember. I corrected it at the time. I should have saved it and
should a similar situation arise in the future I will do so.
Here's the lambda in which the indicated errors used to be if that's any help.
It iterates through a circular list of circular lists.
auto log_serviceorder = [&]() {
const char* F = "%2d. %c[%d] %s id=%d\n";
$LOG(log, BP, TTINF, "service order for %d feeds follows:\n", feedcount);
for(int i=0; i < feedcount; i++) {
circlist<tt::feedhdlr*>::node* feednode =
feedgroups.next()->content.next();
tt::feedhdlr* feed = feednode->content;
$LOG(log,BP,TTINF,F, i,
feed->venue(),feednode->id,feed->name(),feed->id());
}
} ;

I was winking at Matthias... As he knows well, a reduced testcase (say, below
100 lines) would help a lot, if/when you can.

--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-08-25 02:00:47 UTC ---
Here is one which is an ICE on valid code:
int open()
{
int *x2feed_i = 0;
auto insert_feed = [&](unsigned char venue, int* newfeed)
{
for(int x2feed_i = 1; 0; ) ;
x2feed_i = newfeed;
}
}
The only reason why the original was invalid was the invalid use of x2feed_i
inside the loop as I think the int should have been auto.
