Travis Vitek updated STDCXX-436:
--------------------------------
Attachment: 18.limits.stdcxx-436.cpp
Updated regression test compiles a simple program that simulates getconf and
then uses that program to get the values to compare against. The alternative
was to just invoke getconv as suggested, but that didn't work on windows, and
getconf on some platforms doesn't provide values for all constants [LONG_MIN
and LONG_MAX on linux is one example].
> [Linux] MB_LEN_MAX incorrect

> Key: STDCXX-436
> URL: https://issues.apache.org/jira/browse/STDCXX-436
> Project: C++ Standard Library
> Issue Type: Bug
> Components: 18. Language Support
> Affects Versions: 4.1.3
> Environment: gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)
> Reporter: Mark Brown
> Assignee: Travis Vitek
> Priority: Critical
> Fix For: 4.2

> Attachments: 18.limits.stdcxx-436.cpp, LIMITS.cpp.patch,
> stdcxx-436.patch

> On my Linux system MB_LEN_MAX is normally defined to 16 but when I use the
> macro in a program compiled with stdcxx the macro evaluates to 1. The test
> case goes like this:
> $ cat test.cpp && make CPPOPTS="-DGETCONF_MB_LEN_MAX=`getconf MB_LEN_MAX`"
> test && ./test
> #include <assert.h>
> #include <limits.h>
> int main ()
> {
> assert (MB_LEN_MAX == GETCONF_MB_LEN_MAX);
> }
> gcc -c -I/home/mbrown/stdcxx/include/ansi -D_RWSTDDEBUG
> -I/home/mbrown/stdcxx/include -I/home/mbrown/stdcxx-gcc-4.1.1-11s/include
> -I/home/mbrown/stdcxx/examples/include -DGETCONF_MB_LEN_MAX=16 -pedantic
> -nostdinc++ -g -W -Wall -Wcast-qual -Winline -Wshadow -Wwrite-strings

> gcc u.o -o u -L/home/mbrown/stdcxx-gcc-4.1.1-11s/lib -lstd11s -lsupc++ -lm
> test: test.cpp:6: int main(): Assertion `1 == 16' failed.
