Initially reported by Matt Diephouse as {{{ ../../parrot -t1 tcl.pbc
2>file.trace}}}
I tried to whittle this down, and got this far:
{{{
.include 'languages/tcl/src/macros.pir'
.namespace [ 'TclExpr'; 'PIR'; 'Grammar' ]
.include 'languages/tcl/src/grammar/expr/past2pir.pir'
.cloneable()
.sub class_init :anon :load
.end
.sub set_string_native :vtable
.end
}}}
pulling out anything here, or including the .includes seems to make the
segfault go away. -G has no effect on the segfault.
Here's the backtrace:
{{{
