Thanks to Eric Pruitt <eric.pruitt@gmail.com> for + the bug report. + + * field.c (purge_record): For each $n field variable, if valref > 1 + and it has not already been malloced, make a copy of the string, since + $0 is about to be reset. + * interpret.h (Op_store_field): We must call the assign function + before unref, since we must copy any non-malloced $n string values + before freeing $0. + 2017-11-09 Arnold D. Robbins <arnold@skeeve.com> * main.c (usage): Add a note to not post bugs in comp.lang.awk. |
