Bug ID: 57426
Summary: Application core dumps at
__gnu_cxx::__exchange_and_add
Product: gcc
Version: 3.4.3
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rajagopal.maddi at plintron dot com
We have an application; compiled with "gcc 3.4.3" on "SunOS solaris2 5.10
Generic_144488-07 sun4v sparc SUNW,SPARC-Enterprise-T1000".
The application dumps core on the execution of a destructor. The same piece of
code runs quite fine many times, but it rarely dumps. Is there a gcc fix
available?
A loadobject was found with an unexpected checksum value.
See `help core mismatch' for details, and run `proc -map'
to see what checksum values were expected and found.
