Before the patch the generic I/O layer held an + unannounced reference to the interp result to store the read + line into. This unfortunately has disastrous results if the + channel driver executes a tcl script to perform its operation, + this freeing the interp result. In that case we are + dereferencing essentially a dangling reference. It is not truly + dangling because the object is in the free list, but this only + causes us to smash the free list and have the error occur later + somewhere else. The patch simply creates a new object for the + line and later sets it into the interp result when we are done + with reading. + 2002-01-16 Mo DeJong <mdejong@users.sourceforge.net> * unix/tcl.m4 (SC_LOAD_TCLCONFIG): |
