|
| Could somebody with access to an alpha machine please verify this?
| You can enable a verbose build with the port's VERBOSE_BUILD option.

|
| 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,

I'm unable to reproduce the error on my DS10 using an unmodified (cpu
wise) /etc/make.conf
