16717 – [3.4 Regression] [unit-at-a-time] __attribute__((constructor)) broken in C++
Description Andris Pavenis 2004-07-26 16:32:48 UTC
__attribute__((constructor)) doesn't work in C++ for both gcc-3.4.1 and
gcc-3.5.0 20040725 when optimization level -O2 is being used.
All seems to work Ok with gcc-3.3.4.
-------------------- bug.cc ----------------------
#include <stdio.h>
void hello (void) __attribute__ ((constructor));
void hello (void) { printf ("Hello world\n"); }
int main (void) { return 0; }
---------------------------------------------------
g++ -O2 bug.cc -o bug
./bug
works with gcc-3.3.4, but not with gcc-3.4.1 and 3.5.0 20040725
(Initially bug were reported for target i586-pc-msdosdjgpp)
