Hello
We are using the riscv-gnu-toolchain and used -pg to do the profiling on the remote target board . The gmon.out is produced but its not been able to visualize in the Eclipse Linuxtools GPROF viewer plugin.

The viewer throws an end of file exception while decoding the histogram.

The same gmon.out was able to generate output using gprof2dot using graphviz

Attached is the gmon.out and output from gprof2dot.

The OS on which Eclipse is installed is Ubuntu 19.x

Target is a RISCV board.

Attached is the gmon.out and samples.png

The error occurred is below.

!ENTRY org.eclipse.linuxtools.gprof 4 4 2019-11-25 18:00:55.663
