...race below. As you can see, R seems to have been busy calling R_GetTraceback() and a bunch of subsidiary deparse functions. But, at that point I'm done with recover(), and when stop() finally finishes NOTHING else has been printed out - no additional traceback, nothing. So why are we calling jump_to_top_ex() with traceback=TRUE, what good does the call to R_GetTraceback() do? That jump_to_top_ex() code only calls R_GetTraceback() when R_Interactive or haveHandler are true. I am certainly running interactively here, and I did define a handler with options("error"=). But AFAICT, my handler...

...ourced, meaning that the object "foo" does not exist, findFun never returns. Instead the segfault occurs at line 719 in errors.c at the LONGJMP statement. Setting a breakpoint at erros.c:719, the backtrace looks like this (will wrap poorly): 8<------------------------ Breakpoint 2, jump_to_top_ex (traceback=TRUE, tryUserHandler=TRUE, processWarnings=TRUE, resetConsole=TRUE, ignoreRestartContexts=FALSE) at errors.c:719 719 LONGJMP(R_ToplevelContext->cjmpbuf, 0); (gdb) bt #0 jump_to_top_ex (traceback=TRUE, tryUserHandler=TRUE, processWarnings=TRUE, resetConsole=TRUE, i...

...sable for the remainder of its life. As far as I've been able to tell, the values set with setTimeLimit() are checked in R_ProcessEvents(), which is defined separately in gnuwin32/system.c and unix/sys-unix.c. If a time limit is exceeded, it error()s out. That in turn percolates up and through jump_to_top_ex(), as defined in main/errors.c, which eventually calls GEonExit() in main/engine.c, a function meant to reset some state on graphics devices and which from the look of it and its comments was added to fix a similar bug with recordGraphics(). I've added a single line to GEonExit(), to also rese...
