Bug ID: 67696
Summary: libbacktrace prints C++ demangled name for Fortran
symbol
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: Joost.VandeVondele at mat dot ethz.ch
Target Milestone: ---
The backtrace printed on abort can contain demangled names, instead of the
Fortran symbols. In the example below, cp__b becomes cp(bool) :
> cat test.f90
MODULE foo
CONTAINS
SUBROUTINE cp__b()
CALL ABORT()
END SUBROUTINE
END MODULE
PROGRAM test
USE foo
CALL cp__b()
END PROGRAM
> gfortran -g test.f90 ; ./a.out
Program aborted. Backtrace:
#0 0x7FE4810C6B87
#1 0x7FE4810C79C2
#2 0x7FE481198538
#3 0x4006A3 in __foo_MOD_cp(bool) at test.f90:4
#4 0x4006AC in test at test.f90:10
Aborted
I actually notice the same wrong name is printed if a backtrace is asked in
gdb:
