I have it reproducible on Fedora 20 i686 with plain
|
|
CFLAGS=-g ./configure;make;cd gdb/testsuite;make site.exp;runtest gdb.fortran/dynamic-other-frame.exp
|
|
|
|
Besides that I have updated the testcase with
|
|
gdb_test_no_output "set print frame-arguments all"
|
|
so that there is no longer needed the patch:
|
|
[patch] Display Fortran strings in backtraces
|
|
https://sourceware.org/ml/gdb-patches/2014-07/msg00709.html
|
|
|
|
The fix below has no regressions for me. Unfortunately I do not see why you
|
|
cannot reproduce it.
|
|
|
|
Thanks,
|
|
Jan
