I am trying to compile GCC 4.4.6 using xlc 11.1.0.0 on AIX 6.1 TL-05 SP-2.

I use a bash script to drive the build process and the name of the script is

The bootstrap process has failed at the same place two times and is a
reproducible.
Is this a known issue and is there a fix available? Do you want me to submit
full bug report ?
Thank you for your help and support in this matter.
