From FEDORA_PATCHES Mon Sep 17 00:00:00 2001 From: Fedora GDB patches Date: Fri, 27 Oct 2017 21:07:50 +0200 Subject: Display Fortran strings in backtraces FileName: gdb-fortran-frame-string.patch ;; Display Fortran strings in backtraces. ;;=fedoratest http://sourceware.org/ml/gdb-patches/2014-07/msg00709.html Hi, for Fortran it fixes displaying normal strings also in frames/backtraces: (gdb) frame -> The patch is simple and I do not see why it should not be this way. For C/C++ TYPE_CODE_STRING is not used. I am not aware of Pascal but that language is currently not really much supported in GDB anyway. This was a part of my archer/jankratochvil/vla branch but it is not a part of the Intel VLA patchset as it in fact is completely unrelated to "VLA". No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
