Hi,

Building current gdc-master on a MIPS server (running Debian Jessie, I
don't seem to have access to the Buster node), I can't reproduce the
segfault.  What are the chances of it being QEMU that's the cause?

Also, are you linking to the static or shared libphobos library?

Running the testsuite now, to see if there's any reported failures, but
none so far...

Iain.
