http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45930

   Summary: AIX: c++ -static-libgcc cores on throw/catch
   Product: gcc
   Version: 4.5.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: cvolkm...@orga-systems.com


Created attachment 21986
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=21986
Script with code to show the error.

A c++ program with -static-libgcc crashes on AIX (only) after throw.

> terminate called after throwing an instance of 'DoException'
> ./static-gcc-aix-no-catch.sh[52]: 226008 IOT/Abort trap(coredump)

It works fine without "-static-libgcc" on AIX. GNU/Linux x86 does
not have this problem.

A sample script is attached.

gcc -v
Using built-in specs.

The problem does not happen with gcc-4.5.3 and gcc 4.6.1 on AIX 7.1.
I exepct it's fixed in newer g++ versions.
