While compiling gcj on my msterrebase branch (
https://github.com/Zopolis4/gcj/tree/msterrebase), the compilation fails on
a segfault in prims.cc:

Is this an error within prims.cc? Or is it catching an error from somewhere
else? Should I report this as per the instructions? If so, how do I do that
when the arguments are already set?
