../../src/test/test_eh_algorithms.cpp: In function 'void TestParallelLoopAux() [with ParForBody = SimpleParForBody; Partitioner = const tbb::simple_partitioner':

Seen with 7.2.0-18, 7.2.0-19 and 7.3.0-1.
Seems to have worked with 7.2.0-17,
this is likely a regression introduced in 7.2.0-18.


Seen on amd64, i386, arm64 and armhf,
likely happens on all architectures.
