Hi,
I'm working on a large parallel fortran application which give (sometime) a
segfault. When this error occurs I would like to backtrace the call stack to
know where it takes place but I'm unable to get this information, no more than a
list of memory addresses. I've build a small test-case (with an error in array
dimension creating a segmentation fault in a subroutine ) to investigate
gfortran/gcc options.
With gcc version 4.8.2 using options "-g -fbacktrace -gdwarf-3" I get
./plante
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 0x7F99F71A9AC7
#1 0x7F99F71AA0CE
#2 0x7F99F67A9B2F
Segmentation fault
but addr2line -e ./plante 0x7F99F71AA0CE
returns: ??:0
What have I missed ?
Thanks
Patrick
