glibc bug https://sourceware.org/bugzilla/show_bug.cgi?id=19431
On a WRL8 rcpl x86-64 project with SDK installed, compile tst-malloc-fork-io.c
source environment-setup-core2-64-wrs-linux
{CC} -pthread -g -o /workspace/anca/tst-malloc-fork-io /workspace/anca/tst-malloc-fork-io.c
Deploy the binary on the wrl8 target and test it:
tst-malloc-fork-io
Expected result: several reads for fork tests:
