    cmd/compile: grow stack before test() to avoid gdb misbehavior · 77c51c6c
    David Chase authored
    While next-ing over a call in gdb, if execution of that call
    causes a goroutine's stack to grow (i.e., be moved), gdb loses
    track and runs ahead to the next breakpoint, or to the end of
    the program, whichever comes first.
    
    Prevent this by preemptively growing the stack so that
    ssa/debug_test.go will reliably measure what is intended,
    the goodness of line number placement and variable printing.
    
    Fixes #25497.
