Enclosed is an unofficial patch for a bug in str_gets() in str.c @ pl41. The bug can cause input to be trashed. As far as I can tell the bug has been around for awhile; I've checked all patches back to pl29 and it doesn't appear that any of them introduced it. -steve *** str.c.old Fri Nov 16 20:23:48 1990 --- str.c Sat Nov 17 12:32:11 1990 *************** *** 804,809 **** --- 804,810 ---- if (get_paragraph && oldbp) obpx = oldbp - str->str_ptr; bpx = bp - str->str_ptr; /* prepare for possible relocation */ + str->str_cur = bpx; STR_GROW(str, str->str_len + append + cnt + 2); bp = str->str_ptr + bpx; /* reconstitute our pointer */ if (get_paragraph && oldbp) | Steve Vinoski (508)256-6600 x5904 | Internet: vinoski@apollo.hp.com | | Testability and Diagnostics | UUCP: ...mit-eddie!apollo!vinoski| | HP Apollo Division, Chelmsford, MA 01824 | ...uw-beaver!apollo!vinoski| | I feel crapulous today. |

The bug was introduced in patch 40. -steve | Steve Vinoski (508)256-6600 x5904 | Internet: vinoski@apollo.hp.com | | Testability and Diagnostics | UUCP: ...mit-eddie!apollo!vinoski| | HP Apollo Division, Chelmsford, MA 01824 | ...uw-beaver!apollo!vinoski| | I feel crapulous today. |
