Bug 116112 – app-backup/kdar chrashes when compiled with '-Os'

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ruben Jenster 2005-12-19 17:58:36 UTC]

Trying to get kdar working I figured out that kdar shouldn't be compiled with CFLAGS="-Os". At least for me this leads to constant crashes. When trying to open an existing dar archive kdar segfaults with:

*** glibc detected *** double free or corruption (fasttop): 0x085bb110 ***
Der Wecker klingelt

I added 'filter-flags -Os' to the ebuild and kdar works fine now.

Regards,
Ruben

kdar-2.0.6.ebuild  with filtered flags

Maybe one should change the revision number.

Kdar also crashes when I open an existing dar file, using both 2.06 and 2.07.  Unfortunately, I am not techy enough to try the new ebuilds that Ruben created.

Thanks to Ruben's encouragement, I removed the "-0s" option from CFLAGS and recompiled kdar-2.0.7.ebuild, and it worked.  Thanks for the tip Ruben.  My emerge --info file is below (after I removed "-0s").  Hope this helps...

fixed in cvs. thanks

[Comment 6 Carsten Lohrke (RETIRED) 2006-08-16 17:42:27 UTC]

filter-flags is not appropriate, as it just removes the flag causing kdar to be built without any -Ox optimization.

[Comment 7 Carsten Lohrke (RETIRED) 2006-08-16 17:43:42 UTC]

Please use  replace-flags "-Os" "-O2"  instead.
