Package: libc6
Version: 2.13-15
Severity: normal

Hello,

The test suite of ocaml-extunix 0.0.3-1 fails on armel because the
following program:

  #include <execinfo.h>

  int main() {
    void *buffer[100];
    return backtrace(buffer, 100);
  }

returns 0. It returns with a non-zero status (3 everywhere I've tried
myself) on all other release architectures.

Is that expected?


Cheers,

Stéphane

Given backtrace() works correctly when compiled with -funwind-tables, I
guess this bug can be closed. I am doing that with this mail, feel free
to reopen it if you disagree.
