vcmap__error_handling_oom_0__none test fails

[igchor]

This test is introduced in #617

I have made a reprocuder (with only tbb in version 2019~U8-1) and it looks like this binary fails (with segfault) only when all of following are true:

• compiled with clang (I tested on clang-9.0.0-2)
• linked with libunwind (version 1.2.1-9)
• compiled with -O2

I'm not sure where is the problem yet.

#include <sys/time.h>
#include <sys/resource.h>

#include <iostream>

#include <tbb/concurrent_hash_map.h>

#include <dlfcn.h>
#include <stdio.h>

#define MB (1024 * 1024)
#define HEAP_LIMIT_SIMULATE (100 * MB)

typedef tbb::concurrent_hash_map<std::string, std::string,
			 tbb::tbb_hash_compare<std::string>> map_t;

int main(int argc, char *argv[])
{
	const struct rlimit heap_limit = { HEAP_LIMIT_SIMULATE, HEAP_LIMIT_SIMULATE };
	auto err = setrlimit(RLIMIT_DATA, &heap_limit);
	if (err) {
		fprintf(stderr, "Unable to set heap limit.\n");
		return 1;
	}

	map_t map;

	size_t cnt = 0;
	while (1) {
		try {
			map_t::value_type kv_pair{
					std::to_string(cnt),
					std::string(cnt + 1, 'a')};

			map.insert(kv_pair);
		} catch (std::bad_alloc &) {
			std::cout << "OOM at " << cnt << std::endl;
			return 1;
		}


		cnt++;
	}

	return 0;
}

probably to verify by @vinser52 ?

I was able to reproduce this issue only with libunwind in version from ubuntu repository (19.10 and 20.04)

Cannot reproduce with libunwind 1.2.1 (or newer) built from source.

Closing since not reproducible on newer versions
