Emacs worked fine on RHEL + 5.5, but it crashed due to memory corruption on Solaris 10 with + Sun C 5.11. Emacs normally ORs 3-bit tags into their low-order + bits that are otherwise zero. This tagging is optional inside + Emacs but is preferred and is used when __attribute__ ((__aligned + (8))) works, as it does with both recent-enough GCC and with Sun C + 5.11. However, Sun C 5.11 is not GCC and does not #define + __GNUC__ and __GNUC_MINOR__. + + When I added the getloadavg module to Emacs, it brought in + stdlib.in.h, which contained this fragment: + + #ifndef __attribute__ + # if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 8) + # define __attribute__(Spec) /* empty */ + # endif + #endif + + When files that include were compiled with Sun C 5.11, + the above code disabled __attribute__ ((__aligned (8))), which + caused variables to not be properly aligned, which eventually led + to the pointer corruption mentioned above. (This was a bit hard + to diagnose, unfortunately.) + + Several "#define __attribute__(X) /* empty */" code snippets need + to be eradicated from Gnulib to work with non-GCC compilers that + support __attribute__. The Autoconf way to do this is to test for + each kind of attribute that we want support for, and selectively + enable that in source code. + + Fix this problem just for stdlib.h, by adding a test for the + __noreturn__ attribute, and change stdlib.in.h to use that test + when needed. This technique can be easily generalized to the + other *.in.h files and attributes, and a similar technique can be + used for *.h and *.c files. This patch is enough to solve the + problem for Emacs + getloadavg, and I thought I'd publish it for + feedback before undertaking further, similar fixes in other + modules. + + This patch does not arrange to #define HAVE_ATTRIBUTE_NORETURN + because it's not needed for stdlib.h. It merely substitutes the + value directly into stdlib.h. We may well need to #define it, or + similar symbols, for other modules, but it's nice to also have an + option to not #define it for applications like Emacs that do not + need it. + + * lib/stdlib.in.h (__attribute__): Do not #define. + (_GL_ATTRIBUTE_NORETURN): New macro, which in stdlib.h needs to + be defined only if the _Exit module is also used. + * m4/_Exit.m4 (gl_FUNC__EXIT): Require gl_ATTRIBUTE_NORETURN. + * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Subst + HAVE_ATTRIBUTE_NORETURN and default it to 1, its value on GNU + platforms. + * modules/_Exit (Files): Add m4/attribute.m4. + * modules/stdlib (Makefile.am): Substitute HAVE_ATTRIBUTE_NORETURN. + * m4/attribute.m4: New file. + +2011-02-12 Bruno Haible + + wcsrtombs: Work around bug on native Windows. + * m4/wcsrtombs.m4 (gl_WCSRTOMBS_NULL): Test against mingw bug. + * lib/wcsrtombs.c (rpl_wcsrtombs): When dest is NULL, pass SIZE_MAX + instead of len. + * doc/posix-functions/wcsrtombs.texi: Document mingw bug. + +2011-02-12 Bruno Haible + + mbsrtowcs: Work around bug on native Windows. + * m4/mbsrtowcs.m4 (gl_MBSRTOWCS_WORKS): Require gt_LOCALE_FR.
