I can tickle the bug by using this in a predicate / self->thing_var != "" / one too many times. Although I use that exact construction many times. Changing the probe , or even providing an invalid probe does not change the crash. Commenting out the predicate saves the compile. Comparing self->var to an integer compiles ok, ( while not really making sense in the context). The compiler will segv when asked to produce the IR via 'dtrace -S -ls srcipt.dt' Efforts to reproduce the crash with a reduced dtrace file have been futile and the system is sufficiently custom that sharing the script may not be useful. Has anyone else seen this crash? Has anyone noticed arbitrary size limit on dtrace scripts? [New LWP 103111] Core was generated by `dtrace -v -s drive-lifecycle.dt'.
