[Bug bootstrap/20380] New: bootstrap failure

2005-03-08 Thread o dot flebbe at science-computing dot de 
Bootstrap of gcc-3.4.3 (and 3.4.2) fails with following messages while trying to
create libstdc++.so.6.

I applied the APAR's mentioned in the Platform notes (btw it is a aix51 ML 3)

[Bug libstdc++/42349] New: ifstream broken

2009-12-10 Thread o dot flebbe at science-computing dot de 
Compile this trivial program  

-
#include 
#include 

int main() {
  std::ifstream fin("t3.cpp");
}
-
with

g++ -g -O2 -Wall -pthread t3.cpp

Running this program dumps core.

Leaving out the option -pthread it does not abort and works o.k.

Root cause seems to be that the std::ifstream class has different size with and
without -pthread (i.e. -DTHREAD_SAFE) since definition of ifstream member
std::__c_lock ==  __gthread_mutex_t is different with and without -pthread.

This is an AIX only symptom. __c_lock is an int without threads and posix_lock
with threads.

Since there is only one libstdc++ for both with and without threads weird
things will happen.

-- diagnosis program --
#include 
#include 

int main() {
  printf( "%ld\n",sizeof( std::ifstream));
  printf(" %ld\n", sizeof( __gthread_mutex_t));

}

Output with -pthread
 296
 52
--- without
248
 4



I would propose to compile gcc code always with THREAD_SAFE alway on.

OH NO! 

You are right! Can't believe it ...

Sorry for that. Putting it myself as INVALD 

Please close
