Hi,
I am the maintainer of that port, and I just received a port build error
log from Kris.
It seems the devel/boost port is triggering a g++ bug on alpha: While
other c++ compile fine, cregex.cpp seems to cause g++ to consume all
virtual memory.
Could somebody with access to an alpha machine please verify this?
You can enable a verbose build with the port's VERBOSE_BUILD option.
The log shows that g++ is optimizing for a specific CPU. Is that the
cause for the error, i.e. does it work without these optimizations?
Given, that it's really a g++ bug: How should I proceed from here?
File a FreeBSD PR? File a gcc bug report?
Thanks in advance for your help,
Simon
