[Bug target/26052] cygwin's defnes does not honor the -undef option

[Bug libstdc++/24196] New: Using string instances to pass arguments to dlls fails
Hello,
I noticed the following problem while porting an internal C++ application
from linux to Cygwin. If a std::string instance created in one module
(exe or dll) is passed to another say as an argument of a function call,
the program crashes or hangs. I did debug for a while and it turned
out that it is not the program itself that causes the crash - the cause
lies in the std::string implementation, the fact that libstdc++ is
provided as a static archive and that it is compiled without
_GLIBCXX_FULLY_DYNAMIC_STRING defined.
What happens is that each module which links agains libstdc++ get its very
personal copy of the class member _S_empty_rep_storage. Now since
_GLIBCXX_FULLY_DYNAMIC_STRING is not defined an empty string instance i.e.
one that is created by the default constructor of std::string gets a
pointer to _S_empty_rep_storage i.e. the actual allocation of memory is
delayed until memory is really needed. If _GLIBCXX_FULLY_DYNAMIC_STRING is
defined each string instance would get a pointer to a newly heap
allocated block of memory instead . Now look at the ouput of gdb and nm
used on the attached testcase:
[EMAIL PROTECTED] ~/src/testcase/tc
$ nm dll.dll | grep _S_empty_rep_storage
1000c030 d .data$_ZNSs4_Rep20_S_empty_rep_storageE
1000c030 D __ZNSs4_Rep20_S_empty_rep_storageE
[EMAIL PROTECTED] ~/src/testcase/tc
$ nm main.exe | grep _S_empty_rep_storage
00442120 d .data$_ZNSs4_Rep20_S_empty_rep_storageE
00442120 D __ZNSs4_Rep20_S_empty_rep_storageE
===
Breakpoint 1, main (argc=1, argv=0x10042980) at main.cc:9
9 {
(gdb) n
10string s, s1;
(gdb)
12export1 (s);
(gdb) print s
$1 = {static npos = 4294967295, _M_dataplus = {> =
{> = {}, },
_M_p = 0x44212c ""}}
(gdb) print s1
$2 = {static npos = 4294967295, _M_dataplus = {> =
{> = {}, },
_M_p = 0x44212c ""}}
===
Here the two strings share _S_empty_rep_storage.
===
(gdb) step
export1 ([EMAIL PROTECTED]) at dll.cc:7
7 string s1;
(gdb) n
9 s1.push_back ('A');
(gdb) n
10s.push_back ('A');
(gdb) print s
$3 = (string &) @0x22eea0: {static npos = 4294967295,
_M_dataplus = {> = {> = {}, }, _M_p = 0x44212c ""}}
(gdb) print s1
$4 = {static npos = 4294967295, _M_dataplus = {> =
{> = {}, },
_M_p = 0x10042aec "A"}}
(gdb)
===
Here s1 points to the dll local _S_empty_rep_storage.
The _M_p member of _M_dataplus is pointing to different copies of
_S_empty_rep_storage - one stored in the executable which calls the dll
and another one in the dll itself.
Now the second push_back() call in export1 () will end up calling
_M_mutate() to actually allocate storage. _M_mutate() will call
_M_rep()->_M_dispose() which will end up free()-ing the memory reserved
for _S_empty_rep_storage in the main exe. There is a check to prevent
free()-ing
_S_empty_rep_storage:
#ifndef _GLIBCXX_FULLY_DYNAMIC_STRING
if (__builtin_expect(this != &_S_empty_rep(), false))
#endif
but it doesn't work well in the case when a string instance created
in one module is passed to another and libstdc++ is statically linked
because of the fact that each module has its own copy
_S_empty_rep_storage.
Can we get this fixed ?

[Bug ada/20530] gnatlink does not respect -mno-cygwin
--- Additional Comments From gerrit at gcc dot gnu dot org 2005-06-08 12:40 --- >> According to >> http://gcc.gnu.org/onlinedocs/gcc-3.4.3/gcc/Option-Index.html#Option-Index >> >> -mno-cygwin is not a FSF option, so closing this PR. This option just triggers gcc to use other lib and include paths, as they are defined in the specs. So it seems gnat doesn't use the specs when linking. Note that it works quite well with include paths when compiling the source? I will provide a workaround in the upcoming release of cygwin gcc-3.4.4, in addition to -mno-cygwin another flag is needed then: --RTS=no-cygwin This will cause gnat to pick up the right runtime if the gcc-mingw-ada package is correctly installed. Then there is a new subdirectory in i686-pc-cygwin/3.4.4 named no-cygwin with symlinks to the mingw runtime: /---3.4.4 | /---adainclude | /---adalib | /---no-cygwin | +---adainclude | +---adalib $ gcc -v -c --RTS=no-cygwin -mno-cygwin hello_a.adb Reading specs from /usr/lib/gcc/i686-pc-mingw32/3.4.4/specs Configured with: /gcc/gcc-3.4.4/gcc-3.4.4-1/configure --verbose --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-languages=c,ada,c++,d,f77,java,objc --enable-nls --without-included-gettext --enable-version-specific-runtime-libs --without-x --enable-libgcj --disable-java-awt --with-system-zlib --enable-interpreter --disable-libgcj-debug --enable-threads=posix --enable-java-gc=boehm --disable-win32-registry --enable-sjlj-exceptions --enable-hash-synchronization --enable-libstdcxx-debug : (reconfigured) Thread model: posix gcc version 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) /usr/lib/gcc/i686-pc-mingw32/3.4.4/gnat1.exe -quiet -dumpbase hello_a.adb -mno-cygwin -mtune=pentiumpro -fRTS=no-cygwin hello_a.adb -o /tmp/ccqn0PMb.s /usr/lib/gcc/i686-pc-mingw32/3.4.4/../../../../i686-pc-mingw32/bin/as.exe -o hello_a.o /tmp/ccqn0PMb.s $ gnatbind -v -aO./ --RTS=no-cygwin -I- -x hello_a.ali GNATBIND 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) Copyright 1995-2004 Free Software Foundation, Inc.

--- Additional Comments From gerrit at gcc dot gnu dot org 2004-11-21 16:30 --- (In reply to comment #1) > Text mode is the default at least according to C89 so the bug is in cygwin and not GCC. If you want a file to be mode 'A' then read/write it in this mode explicitly. You cannot expect the underlying OS to know who is reading/writing a file and how to do it without explicitly telling the OS what is expected. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18547
