Package: gnat-4.6 Version: 4.6.2-4 Severity: important Tags: patch Usertags: hurd User: debian-h...@lists.debian.org
Hello, Trying to find the problems with gprbuild, see bug #673015, the traceback function used for GNU/Hurd caused a segfault for gprconfig. Digging further revealed that the GNU/Hurd stack frame does not seem to be static enough to define USE_GENERIC_UNWINDER in gcc/ada/tracebak.c. However, USE_GCC_UNWINDER works (and the dummy version of course)! The patch is inlined below. --- a/src/gcc/ada/tracebak.c 2011-09-19 11:10:42.000000000 +0200 +++ b/src/gcc/ada/tracebak.c 2012-07-17 08:46:29.000000000 +0200 @@ -320,7 +320,7 @@ /* Starting with GCC 4.6, -fomit-frame-pointer is turned on by default for 32-bit x86/Linux as well and DWARF 2 unwind tables are emitted instead.
