15 | I have it reproducible on Fedora 20 i686 with plain | |
16 | CFLAGS=-g ./configure;make;cd gdb/testsuite;make site.exp;runtest gdb.fortran/dynamic-other-frame.exp | |
17 | ||
18 | Besides that I have updated the testcase with | |
19 | gdb_test_no_output "set print frame-arguments all" | |
20 | so that there is no longer needed the patch: | |
21 | [patch] Display Fortran strings in backtraces | |
22 | https://sourceware.org/ml/gdb-patches/2014-07/msg00709.html | |
23 | ||
24 | The fix below has no regressions for me. Unfortunately I do not see why you | |
25 | cannot reproduce it. | |
