As every new technology, it needs some time to evolve.  Nevertheless, it is an important tool to mitigate the effects stack overflow attacks can produce.  Besides, this was no code generation error, but a simple abort() in the compiler sources to handle unforseen circumstances.  Gcc is full of those, as is our kernel.  It is just not easy to make such a big project completely bug-free.

    Another propolice issue?  I'm about ready to huck that thing out 
    the window.

I spoke to soon.  Thanks to corecode for tracking down a fix for this
problem.

This is a problem with propolice, an add-on to gcc.  Whatever this problem
is, it's not going to be fixed in the 3.4.x gcc stream.  The patches I sent
you disable propolice while compiling powerdns-recursor.

I'm hoping that the propolice support in gcc-4.1 will not have this problem,
but more investigation is warranted.

fixed

Id like to open this bug again because I get the same thing but on 
wip/powedns-recursor.

does this still happen?

This is a known propolice bug for which we need to look upstream for a fix.

I got this one when compiling net/amule from pkgsrc:
