Perhaps the application binary file is stored on a faulty region of the disk? (This is a complete guess. What is supposed to happen when a program tries to page into memory, but fails?) -- John Gordon A is for Amy, who fell down the stairs gordon(a)panix.com B is for Basil, assaulted by bears -- Edward Gorey, "The Gashlycrumb Tinies"

It's crashing as well but however, GDB does not report SIGKILL anymore but the application instead just dies... :o > > -- > John Gordon A is for Amy, who fell down the stairs > gor...(a)panix.com B is for Basil, assaulted by bears > -- Edward Gorey, "The Gashlycrumb Tinies"

Any clues? :o SIGABRT is raised by calling the abort() system call, or when an assert() evaluates to false. Does your program contain any abort() or assert() calls? -- John Gordon A is for Amy, who fell down the stairs gordon(a)panix.com B is for Basil, assaulted by bears -- Edward Gorey, "The Gashlycrumb Tinies"

Yes, there's abort() calls in a file called memwatch.c - I guess I should have a look at this one... Thanks! Ron

Oh look there, it's a huge file and in the header it says: ** MEMWATCH.C ** Nonintrusive ANSI C memory leak / overwrite detection ** Copyright (C) 1992-2001 Johan Lindh ** All rights reserved. ** Version 2.67 o after all I probably sent myself these signals...Does anyone know anything about this memwatch.c file - gotta make myself smart 1st :)? -- Ron |
