Thanks for the report. Just to be clear to others, this is for the current development version of pqR. The problem shouldn't exist in the last release of 2014-06-19.

Presumably, Rterm writes to R_NilValue, hopefully writing the same data that is already there, since R_NilValue shouldn't change. Perhaps it sets "levels" to zero with SETLEVELS, which I think is the only access function where I didn't put in a check for setting to the existing value.

It should be possible to bypass this by deleting the "const" qualifier on the declaration of R_NilValue_const in src/main/const-objs.c. Keeping R_NilValue read-only would be nice though, since it would detect some bugs.

deleting the "const" qualifier on the declaration of R_NilValue_const in src/main/const-objs.c,but no luck.
after some printf to trace the problem. now in main.c setup_Rmainloop function
if (R_SignalHandlers) init_signal_handlers();
if (!doneit) {
doneit = 1;
R_ReplFile(fp, baseEnv);<<<this cause crash
}

furthermore trace to Eval.c evalv function cause crash,but no idea what happening

on branch 23 windows build ok,thanks

I didn't do anything specific to address this bug, so I think you just got
an unstable development version. These non-release versions aren't
necessarily tested.

I can let you know when I have a somewhat stable and tested version for you
to try (even if not ready for general release).

Hi,

I'm busy on another project for the next couple weeks, but after that I
plan to get back to working on pqR. Trying out Windows builds myself is
one of my priorities, so I hope to figure out these things soon. Thanks
for trying it out!
