Description rroffelsen 2014-05-30 15:18:18 MST 
GCC has decided (contrary to the ABI) that stacks should be aligned to 16 byte binderies for x86 processors (see http://sourceforge.net/p/fbc/bugs/659/).

Comment 17 deosbugs.ccb 2023-08-18 08:16:18 MST 
PCR being taken off HOLD for kismet.  Note: this only applies to x86 32-bit.

Comment 19 alarson 2024-07-18 10:09:11 MST 
I thought the intention was not to verify x86 for kismet.  Shouldn't this PCR be placed on hold?
