Bugzilla Bug 118836

+++ This bug was initially created as a clone of Bug #74899 +++

It would appear that I've run into an issue similar to the old -fPIC bug
reported in #74899.  Same error message, anyway.

!!! ERROR: games-emulation/advancemenu-2.4.12 failed.

the above errors occur with gcc-config set to i686-pc-linux-gnu-3.4.5-hardened.
 With i686-pc-linux-gnu-3.4.5-hardenednopie, both packages build just fine. 
Maybe -fno-pic in the CFLAGS would be a workaround?

No that would make it worse. 

Try to regain a register with -fomit-frame-pointer till somebody finds time to
review the code in question. If that fails then you can maybe try -fno-pie

I just rebuilt advancemame and advancemenu.  In both cases,
-fomit-frame-pointer did not help.  -fno-pie did successfully build both
packages, with a warning and a QA notice about TEXTREL stuff.

Well, it seems like the pic patch for advancemame was dropped at some point. 
No idea why.  I added it back in for 0.106.0 so can you give that a try please?

0.106.0 builds fine for me with gcc-3.4.6-hardened.  Thanks!

Great!  Thanks for testing.  I'll try to get the pic patch in upstream and make
sure it doesn't get dropped going forward.

well that patch ignores the real issue ... try and fix the inline asm to be PIC
