index-parse.c:1256:6: error: assuming pointer wraparound does not occur when comparing P +- C1 with P +- C2 [-Werror=strict-overflow]
No idea why this happens:
index-parse.y: In function 'yyparse':
index-parse.c:1256:6: error: assuming pointer wraparound does not occur when comparing P +- C1 with P +- C2 [-Werror=strict-overflow]
if (yyss + yystacksize - 1 <= yyssp)
^
It only happens on one machine, and not on any others, even
though they have similar versions of gcc and bison installed.

I should clarify .. Of course I understand what the error message
means and why it happens. The mystery is that it only happens...

[LLVMdev] problem trying to write an LLVM register-allocation pass
I have a new problem: Register RBP is used in a function foo. (I am not
allocating RBP to any virtual register, the instances of RBP in function
foo are in the machine code when my register allocator starts.)
Function foo calls function bar. Register RBP is not saved across the
call, though it is live after the call. Function bar includes a virtual
register. The code that I'm using to
