7093	"Building ""system"" segfaults on AIX 6.1 / vacpp"	Martin Baute <solar@…>	Vladimir Prus	"Machine:

- AIX 6.1, 4-CPU PowerPC_POWER7

Compiler:

- IBM XL C/C++ for AIX, V11.1

Steps to reproduce:

- unpack Boost source tarball
- `./bootstrap.sh --with-libraries=system`
- `./b2`

Observed behaviour:

{{{
$ ./bootstrap.sh --with-libraries=system

not found.

Bootstrapping is done. To build, run:

    ./b2
    
To adjust configuration, edit 'project-config.jam'.

Also tried:

- `./b2 address-model=64` (same behaviour, with `release/address-model-64/threading-multi` as last output instead of `release/threading-multi`)

Observed since:

- boost-1.50.0. (Worked fine with boost-1.49.0.)

Unfortunately I am not familiar enough with either AIX 6.1 nor the Boost building process to know what other information might be helpful for you, or how to get them, but am willing to be talked through additional debugging steps and providing relevant logs or whatnot."
