Segmentation fault when using fgt2xml

[Senyai]

Hi! I'm getting segmentation fault when using fgt2xml (or fgt2xml_debug). `0x000055555564220f in fgt_record_processor::dump_trace (this=0x7fffffffd7e0) at /localdisk/jenkins/workspace/FGA_Linux_build/fgatool/src/collector/src/fgt2xml/fgt_record_processor.cpp:1089`. Is there any chance to open source this tool? Otherwise I have no idea how to find out the root cause of the issue.

I have an idea now of what is going on. TBB_USE_PROFILING_TOOLS was enabled on tbb::flow code only and not in other files files that use tbb. After enabling TBB_USE_PROFILING_TOOLS globally, I was able to get valid fgt2xml output. Anyway, segmentation fault must be fixed.

Hi,

Thanks for providing the zip file of the FGT traces and triaging the possible reason as to why this might be happening. This will help us find a fix  when only partial set of files are compiled with TBB_USE_PROFILING_TOOLS.
