Package: gnat-4.6

Severity: important
Tags: patch
Usertags: kfreebsd
User: debian-bsd@lists.debian.org
Hello,
When building polyorb-2.8~20110207 for GNU/kFreeBSD it segfaults, see
https://buildd.debian.org/status/fetch.php?pkg=polyorb&arch=kfreebsd-i386&ver=2.8~20110207-3&stamp=1338587039
Building non-stripped versions of libgnat-4.6.so.1 and libgnarl-4.6.so.1
the gdb backtrace revealed that the stack unwinder with
USE_GENERIC_UNWINDER in gcc/ada/tracebak.c is the cause (as for
GNU/Hurd).
With USE_GCC_UNWINDER the build works, except for a linker error later
on, see separate bug reports for gnat-4.6 of gcc-interface/Makefile.in
changes for Hurd and kFreeBSD!
The patch is inlined below. Preferably it could be applied by modifying
the last part of the recent patch: ada-symbolic-tracebacks.diff
