[Bug libstdc++/26094] New: Segmentation fault in Linux 7.1 GCC 3.1 Kernel 2.4.9-45lxset34smp

[mahek2k1 at yahoo dot com]

Hi ALL,

Machine A : Linux 7.1 GCC 3.1 Kernel 2.4.9-45lxset34smp
Machine B : Linux 7.1 GCC 3.1 Kernel 2.4.2-2

The following piece of code when run and compiled in Linux7.1 Machine A, runs
fine, also compiled and run in Machine B, runs fine.

But when the code is compiled in Machine A and run in Machine B, it crashes
with segmentation fault:

--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

int main () {
ifstream is;
is.open ("test.txt");
if ( (is.rdstate() & ifstream::failbit ) != 0 )
printf( "Error opening 'test.txt'\n");
return 0;
}

Any IDEAS??

Rgds,
LearningAllTheTime

Thanks for the inputs, sorry for making it confusing, the linux is Redhat 7.1
