Bug 250364 – sys-libs/glibc-2.9_p20081201 breaks sci-physics/root

• Product: Gentoo Linux
• Status: VERIFIED NEEDINFO

[Description Till Matthiesen 2008-12-09 12:22:44 UTC]

Hello,

I accidentially upgraded the glibc to the newest 
available version 2.9_p20081201. 

I'm not able to run any of my ROOT (sci-physics/root) programs anymore,
always ending up with a SEGFAULT.

 *** Break *** segmentation violation
Segmentation fault

Currently I'm running sci-physics/root-5.20.00-r1
Not sure if this is also the case with 5.20.00-r2 as this ebuild didn't work
on my machine. As far as I can see from the Changelog I wouldn't expect
5.20.00-r2 to behave any differently.

Reproducible: Always

Steps to Reproduce:
1. emerge sys-libs/glibc-2.9_p20081201
2. emerge sci-physics/root-5.20.00-r1
3. build ROOT testsuite in /usr/share/doc/root-$VERSION/test
4. run 'stress'. At least this one also quits with a SEGFAULT here and works
flawless on a comparable machine and glibc-2.8_p20080602.



I marked this as critical as downgrading of glibc is not possible/advisable.

Hi,

I tested root-5.20.00-r2 on both ~x86 and ~amd64 with glibc-2.9_p20081201, and the stress test ran fine.
Please try root-5.20.00-r2 and if it doesn't compile, file a new bug with your emerge --info, use flags for root, and build log.

Thanks

5.20.00-r2 builds fine now.

Unfortunately its still SEGFAULTing as described,
showing perfectly the same symptomatics.

If I can provide you with further information, just
let me know.

Thanks again!

all bug reports need `emerge --info` as stated in the bugzilla documentation

also show the output of `emerge -pv root`

if things are still crashing, then you should read the bugzilla documentation in order to setup your system to provide a good backtrace: you've shown symbols, but no function arguments

Issues resolved after update to sys-libs/glibc-2.9_p20081201-r1 for me.

Thanks again.
