A C++ exception of type 'std::ios_base::failure' is being thrown which is not handled by the exception handler

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux 4 - All architectures
  • Red Hat Enterprise Linux 5 - All architectures
  • Red Hat Enterprise Linux 6 - All architectures

Issue

  • A C++ exception of type 'std::ios_base::failure' is being thrown which is not handled by the exception handler
  • Opening a non existing file throws an 'std::ios_base::failure' exception, calling SIGABRT

Resolution

This package "libgcc-4.1-32bit-4.1.2_20070115-0.2.x86_64" has provided its own /lib/libgcc.so.1 file. Restore this file from the provided Red Hat package.

Root Cause

A non standard (third party) /lib/libgcc.so.1 supplied by a third party. This can override (and change) behaviour in the libstdc++ libraries exception handling abilities.

Diagnostic Steps

** The systems /lib/libgcc.so.1 (or /lib64/libgcc*) has been modified.

The rpm database maintains a comprehensive database of the status of installed files. Packages can be validated by RPM using the verify parameter.

# rpm -V libgcc
SM5....T   /lib/libgcc.so.1

These flags show that the following file attributes have been changed. This may differ on your local machine. For more information see this section of the RPM manual.

S is the file size.
M is the file's mode.
5 is the MD5 checksum of the file.
T is the modification time of the file.
