Hi,
some new informations, gcc 4.2.4 is also affected by this, but all gcc
<= 4.2.3 are for sure working right, for 4.2.4 and 4.3.1 tachyon
segfaults, I'm looking for some live cd with gcc 4.3 to see if problem
is also visible in it or not, it seems to appear in gcc trunk
somewhere between 2008-0
Hi,
after some sniffing around, I noticed that for me (see bottom of mail
for gcc version) techyon needs to be compiled with "make linux" (with
disabled threads) or with "-fno-crossjumping -fno-reorder-blocks"
added to "Make-arch" file at line 1134 (linux-thr target, after -O6) -
second is better
I was able to reproduce this on many different machines, all had only
one common case - they had GCC 4.3.1 or later - additional to my
system there is also friends Debian that is affected, as of arch a way
to make it reproducible is to update to latest (pacman -Syu) still
looking for someone with
Hi,
it still breaks on -O3 and -O2 iirc as when I tested... it should be
lowered to -O1 to work always, anyway adding only those 2 mentioned
earlier flags (-fno-crossjumping -fno-reorder-blocks) makes it work, I
though rather about looking for what compiler versions it fails and
patching it in th

Hi again,
was trying to track that segfault in tachyon doctest, it happens
during show(t) in "texture" example, that's in:
t = Tachyon(camera_center=(2,5,4), look_at=(2,0,0), raydepth=6)
t.light((10,3,4), 1, (1,1,1))
t.texture('mirror', ambient=0.05, diffuse=0.05, specular=.9,
opacity=0.9, color

Hi Andrzej,
any kind of seemingly Heisenbug that was hard/impossible to reproduce
has bitten us in the ass down the road, so everybody please report any
seemingly inconsequential or random
oh, and yes - I built it from source

It's 32 bit Arch Linux current, GCC 4.3.1 (patched to snapshot from
2008 06 26), GlibC 2.8
Following Ansrzej's report I tried the same thing. For me the test
always takes 2.0-2.1s but the 5th or 6th time I got the failure:
sage -t devel/sage/sage/modular/ssmod/ssmod.py

Hi,
small report - compiled fine, all tests passed (but that's what was
reported by make test)... looking into test.log there's still segfault
with tachyon test:
sage -t devel/sage/sage/plot/tachyon.pysh: line
1: 2 Naruszenie ochrony pamięci tachyon
/root/.sage//temp/gi
Installed fine and all tests passed, with these flags set:
SAGE_BUILD_THREADS=2
SAGE_PBUILD=yes
