It looks like there is unaligned movdqa read (it should be aligned to 16-byte boundary, but it isn't):

Updated to the lastest version of Hipster yesterday, the Package Manager still crashes.

Could you try updating python package and run package manager? Segfaults should be fixed.

No, this issue is still present.

Isn't it aligned? 0xfffffe28 is just -472. Address at 472 bytes is 32-bit aligned. So, it's something else.
And if it were not aligned, it would be SIGBUS, not SIGSEGV...

The misaligned address is 8043fd4, not 0xfffffe28 (which is misaligned too; it should be 16-byte/128-bit aligned). And I just tested that misaligned movdqa generates SIGSEGV, not SIGBUS.

Hi,

still happens.
Regards.

Still crashes after hipster update on 12/4/2013, same stack in core dump.

However, I'm not sure if hipster has really gotten the illumos updates:
