Summary: SIGFPE (division by zero) in
std::binomial_distribution
Classification: Unclassified
Product: gcc

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org

minimal program to expose the bug in std::binomial_distribution
Hello,
When I explicitly enable floating point exceptions in my code, the program
crashes on SIGFPE inside the std::binomial_distribution. The program works fine
when fp exceptions are not enabled, however, I want them enabled during
development, to help me track errors in my code.
I'm attaching minimal program to reproduce the crash. Compile and run it with:
g++ -std=c++11 -Wall -Wextra -g -o scratch scratch.cpp && ./scratch
This is the output of gcc -v:
Using built-in specs.
