[Virtual-pkg-base-maintainers] Bug#714521: base: (GCC|G++|something else in the toolchain) produces segfaulting code

[Christian Böhme]

Package: base
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?

successfully compiling

---8<---
// #include <cstddef>


int main ( int argc, char * argv[] )
{
        int i = 100;
        int j = i + 4;

        return j;
}
---8<---

as  source.c++  twice with

gcc -g -Wall -o automatic source.c++

and

g++ -g -Wall -o automatic source.c++

and running  automatic  from within  gdb  for each program produced

gdb ./automatic

   * What was the outcome of this action?

Do you need "set solib-search-path" or "set sysroot"?

Quit anyway? (y or n) y

   * What outcome did you expect instead?

non-segfaulting code being generated
