[Monotone-devel] Problems after building monotone

[Justin Patrin]

I'm running Gentoo, pretty much up to date. I was previously running
monotone 0.25 from portage just fine. I decided to try making an 0.27
ebuild and basically just copied the 0.25 one. It built perfectly but
when I ran it I got a segmentation fault. I then downgraded to 0.25
again and I get this:

# monotone
terminate called after throwing an instance of 'std::length_error'
 what():  basic_string::reserve

I tried uninstalling and reinstalling(building) and I still get the same thing.

I then tried downloading the static binary on venge.net. It works
fine. I pulled net.venge.monotone (nice and fast, thanks for the
speedup work) and built from that. Segfault again. GDB shows:

My guess is that some build tool on my system is doing something
incorrectly. I am not using any extreme optimization flags (my CFLAGS
for Gentoo are "-march=athlon -O3 -pipe", no extra flags used for
manual build).

GCC version is:
gcc (GCC) 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)

boot version is 1.33.1.
