[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

"Linux 7.1" that is a new one.

Also 3.1 came out almost 4 years ago.

Please try with Linux and gcc that are still supported.

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

The compiler you are using, 3.1 was a release that was immediately superceeded
by 3.2 because of errors. It is unsupported, as is Red Hat 7.1.

Please put self-contained (ie cut and paste to compiler with no edits) sources
in bug reports. 

I suggest you try again with 3.3, 3.4, or 4.0. Try compiling both as you did
(which was how, by the way) and also with static links (-static). See if one
fails, and the other works. If so, reopen this and provide more details.
