Description
This bug might be linked to #70 Intel OpenMP breaks Gotcha bug.
Intel version used: intel/19.0.3.199
Trying to wrap dgemm_ from mkl I got:
[...]
[44825/44825][gotcha.c:343] - Gotcha wrap completed successfully
Before wrappee dgemm call
./a.out: symbol lookup error: /opt/intel/compilers_and_libraries_2019.3.199/linux/compiler/lib/intel64/libiomp5.so: undefined symbol: ompt_start_tool

Research direction
Start with gotcha.c around line 343 and reproduce the dgemm_ wrapping case using Intel 19.0.3.199 and the reported libiomp5.so error. Read the related Intel OpenMP issue in #70 and trace the wrap completion through the failing symbol lookup. Done means the reported undefined ompt_start_tool failure is resolved or its supported configuration and limitation are documented.
