As of RELEASE_3_1_0-329-geb0ebb2 the t/pmc/structview.t test fails on Linux/386 with:

1..16
ok 1 - 8 bits in one byte
ok 2 - single byte is byte-aligned
ok 3 - byte-aligned single byte is single byte when aligned
ok 4 - allocate an instance
ok 5 - bitpattern gives correct byte
ok 6 - unaligned struct first byte
ok 7 - unaligned struct second byte
Failed allocation of 3219616584 bytes

We highly suggest you notify the Parrot team if you have not been working on
Parrot.  Use parrotbug (located in parrot's root directory) or send an
e-mail to parrot-dev@lists.parrot.org.
Include the entire text of this error message and the text of the script that
generated the error.  If you've made any modifications to Parrot, please
describe them as well.

Version     : 3.1.0-devel
Configured  : Sat Feb 26 19:51:13 2011 GMT
Architecture: i386-linux
Interp Flags: (no interpreter)
Exceptions  : (missing from core)

Dumping Core...
Sorry, coredump is not yet implemented for this platform.

This was compiled with gcc-4.3.2 with no optimization, but changing the optimization level (or even the compiler) didn't make any significant difference.

I was unable to reproduce this on i686/linux/gcc-4.5, but have just recently been able to try i686/linux/gcc-4.4 where the problem does manifest.

This should be resolved in 298b2e2.
