btw.. im using kde-3.4 and ksayit-0.83 from kdeaccessibility-3.4
Maybe you mixed things compiled with gcc-3.3 and gcc3.4? Try doing 'revdep-rebuild -X --soname libstdc++.so.5'
I've seen this problem on a machine that had a borked gcc/glibc upgrade. You need to make sure all of the libraries are build against the newest glibc.
Created attachment 73694 [details, diff] ksayit-3.4.3-invalid_free.patch Proposed patch to work around glibc invalid pointer errors. Works without MALLOC_CHECK_ workarounds.
I have tested the patch and it also works well here, where before I had to use the glibc workaround. I have committed ksayit-3.4.3-r1 and kdeaccessibility-3.4.3-r1 to the tree. I would like to get these stabilised ASAP as the fix is quite simple and works here. Thanks to Chris for providing the patch.
Closing.
