segfaults on FreeBSD 8

[oparoz]

I've tried both 0.4.12 and 0.6.2-pre. V8 version is 3.7.3.

Here is the trace with 0.6.2-pre

The backtrace suggests that you're linking to an external libv8, not the one that comes bundled with Node.

[oparoz]

Indeed, because of issue #982 (last messages). The one bundled with node.js fails to compile.

I can't really help you but I can give you some tips.

obj/release/mksnapshot obj/release/snapshot.cc --logfile "/node-master/out/Release/obj/release/snapshot.log" --log-snapshot-positions
scons: *** [obj/release/snapshot.cc] Error -11

Snapshotting fails with a SIGSEGV for one reason or another. Not insurmountable, ./configure --without-snapshot will skip it (the downside is that node will take slightly longer to start up).

Alternatively, downgrade libv8. We ran into stability issues with 3.7.1 so we downgraded to 3.6.6.7 (it may or may not be caused by #2061 but the issue described in edea412 only manifested itself with 3.7.1).

[oparoz]

Thanks for your help :). I've managed to compile it with the bundled v8.

The problem came from the gold linker (ld gold) which is severely broken on FreeBSD.
