Is anybody experiencing core dumps with PHP and mysql?

I'm no longer able to run my website due to some bizarre
malloc errors:

#0 0x7064b948 in _int_malloc ()
from /lib/libc.so.6
(gdb) where
#0 0x7064b948 in _int_malloc () from /lib/libc.so.6

#6 0x70c3af90 in ?? () from /usr/lib/apache2/modules/libphp4.so
Previous frame identical to this frame (corrupt stack?)

Can anybody help me troubleshoot?

Thanks..

I may have run into this with php-5.x on a ~sparc box. Can you provide
details on your setup (profile, versions of applicable software in use,
output of emerge info)?

Thanks,

You bet.

2x300mhz Usparc-2 (ultra enterprise 2) with 2Gb phys ram
Prom 3.25.0, 2.6.15-r3 kernel, gcc 3.3.6

emerge --version
Portage 2.1_pre5-r4 (default-linux/sparc/sparc64/2005.0,
gcc-3.3.6, glibc-2.3.3.20040420-r2, 2.6.12.3 sparc64)


Hmm.. this isn't right. Looks like one of the crashes munged up my
conversion to 2006.0

I'm going to clean up my profile and re-emerge the system stuff to see
if it is a partial emerge issue that's causing this.

Sometimes, you just need somebody to point you back at the issue
you've been staring at, but with new eyes.

Thanks!

Think I found some of the cause -- my gcc environment was a little snarfy.
gcc32 was pointing to 3.3.6, and gcc64 was pointing to 3.4.5.
re-ran gcc-config to force rebuilding the config files and default
everything to 3.4.5
and am revdep rebuilding right now.

hopefully this will cure the php issue.

Is NPTL ready to go for SPARC? It's lingering in the back of my head
that it's not, but I can't recall exactly why I think that...

Correct me if I'm wrong, but doesn't the "hardened" USE flag require the
"hardened" profile? AFAIK, that profile doesn't exist for SPARC.

In theory you can use hardened without a profile, but it's usually
tricky. In the SPARC case last time we tried it required the
"boundschecking" USE flag on (gcc uses it so you need to rebuild).
YMMV - there's no guarantee this is still working.

As long as you're on a 2.6 kernel and 2006.0 profile up to date
(toolchain upgraded and so on) it works just fine.

Last I recall seeing it was known to be OK for sparc64 but not for
sparc32.

Hmm.

Even without NPTL enabled, I can't get glibc to build:

wormhole ~ # USE="-nptl" nice emerge --pretend glibc

These are the packages that would be merged, in order:

I'm not running the build as hardend now.

But I'll give it a try anyhow. Anything to get this fraking
build to complete successfully.

If you switched from USE="hardened" to non-hardened half-way you will
have issues.
Also it's highly recommended when upgrading <2006.0 profiles to >=2006.0
to rebuild everything with the new gcc, not just revdep-rebuild.

You know, it wasn't clear to me before, but having just gone
through the rebuild, it's now clear:

__gcc__ requires a rebuild with boundschecking.


Sorry if I've mitched and boaned trying to get this to work.

Anyhow, I updated /etc/make.conf with boundschecking as hardened
already existed, and re-ran:

emerge --newuse glibc

which rebuild gcc and glibc in a nice pair.

So I've successfully build glibc 3.4.5. Phew!

I've only I'd figured out earlier about the gcc rebuild.. D'oh!

Thanks again.
