Currently we can't run Parrot with certain IMCC optimizations (by setting TEST_PROG_ARGS, for example, or hacking t/harness because the optimization somehow removes useful context information printed in the Parrot backtrace. $ ./parrot -O t/compilers/imcc/syn/const_24.pir Null PMC access in get_string() $ ./parrot t/compilers/imcc/syn/const_24.pir Null PMC access in get_string() current instr.: 'main' pc 5 (t/compilers/imcc/syn/const_24.pir:11) The difference lies somewhere in Parrot_Context_get_info(), I believe. I don't have the time or capacity to track this down tonight; I was tracking down a potential bug in the IMCC optimizer and thought it would be nice to see if any tests fail with optimizations. -- c
