I know nothing of aliasing... so i don't know what you question is
about.
It is inefficient to choose me for this job, since any C programmer
can explain it. Please ask a C programmer.
> Would row->glyphs[area][i].charpos ever have aliased with area?
(gdb) i ad area
Symbol "area" is a variable in register edx.
Since area is in a register, we know they cannot alias.
At this point, I am almost convinced it has to be a hardware fault (or
maybe a kernel bug that affects process switching). However, I think
someone would have to study the assembler language before really
believing this conclusion, because there is also the chance it could
be a compiler bug.
