Hi, I have a ksh crash coredump that I suspect might have been caused by recursive eval, but at the crash moment, memory is way too corrupted to be certain.
The issue is: sh_eval(Sfio_t *iop, ...) ... static Sfio_t *io_save; ... io_save = iop; /* preserve correct value across longjmp */ ... jmpval = sigsetjmp(buffp->buff,0); while(jmpval==0) ... if(!(mode&SH_FUNEVAL) || !sfreserve(iop,0,0)) { if(!(mode&SH_READEVAL)) sfclose(iop); io_save = 0; ... if(io_save) sfclose(io_save); .... I do not have a reproducer for the crash, but I have a feeling on special conditions, with nested evals, it might call sfclose(io_save) multiple times, or leak if io_save is set to zero in a nested eval.
