[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: 4.2
Environment: gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)
Reporter: Mark Brown
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
-Wno-long-long -Wcast-align test.cpp
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.
Aborted
