The main thing I have been doing over the last month is to make the optree-walking functions in op.c non-recursive and/or non-leaky. In auto-generated code, such as $a.. and things involving arbitrary-deep nesting of braces and parentheses, it's easy during compilation to create a deep optree. Many functions in op.c walk those trees using recursion, which can blow the stack and cause a crash. This is especially noticeable under threads, where each thread by default only gets a relatively small stack. Some functions were modified to malloc() a buffer to keep track, but that could leak if the compiler croaked during tree traversal.
