--- Comment #9 from Ian Lance Taylor <ian at airs dot com> ---
It does work for me on x86_64 GNU/Linux. The big stack allocation is handled
by the split-stack support.
This of course leaves the question of why it is making such a large stack
allocation to begin with. It seems to be because of the line
var t = T{si, ai, pai, sq, aq, paq, sib, aib, paib, sqb, aqb, paqb}
This is being compiled into code that assembles a T value on the stack and then
copies it into the variable t. Unfortunately the type T includes fields like
aib [100000]int
paib *[100000]int
sqb []quad
aqb [100000]quad
paqb *[100000]quad
which are very very large.
