Bug ID: 98390
Summary: AIX: exceptions in threads: IOT/Abort trap(coredump)
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: stefan at bytereef dot org
Target Milestone: ---
The following test case is extracted from a larger program. When repeated
often enough, it terminates with: IOT/Abort trap(coredump)
Confirmed with g++ (GCC) 7.2.0 and g++ (GCC) 10.2.0 on gcc119.fsffrance.org.
test.cc:
========================================================================
#include <stdexcept>
#include <thread>
#include <vector>
class suntime_error : public std::runtime_error {
using std::runtime_error::runtime_error;
};
static void
doit()
{
try {
throw suntime_error("this is an error");
}
catch (const suntime_error& err) {
(void)err;
}
}
static void
do_threads()
{
const size_t n = 100;
std::vector<std::thread> t(n);
for (size_t k = 0; k < n; k++) {
t[k] = std::thread(doit);
}
for (size_t k = 0; k < n; k++) {
t[k].join();
}
}
int
main()
{
do_threads();
return 0;
}
========================================================================
doit.sh:
========================================================================
#!/bin/sh
while ./test; do
:
done
========================================================================
$ g++ -pthread -Wall -Wextra -std=gnu++11 -pedantic -O0 -g -o test test.cc
$ ./doit.sh
