From FEDORA_PATCHES Mon Sep 17 00:00:00 2001 From: Fedora GDB patches Date: Fri, 27 Oct 2017 21:07:50 +0200 Subject: gdb-bz568248-oom-is-error.patch ;; Out of memory is just an error, not fatal (uninitialized VLS vars, BZ 568248). ;;=push+jan: Inferior objects should be read in parts, then this patch gets obsoleted. http://sourceware.org/ml/gdb-patches/2010-06/msg00005.html Hi, unfortunately I see this problem reproducible only with the archer-jankratochvil-vla branch (VLA = Variable Length Arrays - char[var]). OTOH this branch I hopefully submit in some form for FSF GDB later. In this case (a general problem but tested for example on Fedora 13 i686): int main (int argc, char **argv) { char a[argc]; return a[0]; } (gdb) start (gdb) print a ../../gdb/utils.c:1251: internal-error: virtual memory exhausted: can't allocate 4294951689 bytes. It is apparently because boundary for the variable `a' is not initialized there. Users notice it due to Eclipse-CDT trying to automatically display all the local variables on each step. Apparentl no regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu. But is anone aware of the reasons to use internal_error there? I find simple error as a perfectly reasonable there. (history only tracks it since the initial import) IIRC this idea has been discussed with Tom Tromey, not sure of its origin. I understand it may be offtopic for FSF GDB but from some GDB crashes I am not sure if it can happen only due to the VLA variables.
