doxygen_1810_vm61_cpu_4_threads4_gdb_bt_data.log
* The attached log file keep trace of the random SIGSEGV of doxygen
while call in loop as detailed below.
* as already reported before such failure reported only
when guest configured like: 4 threads/core (as per lscpu in log)
* gdb reported regs confirm reason of SIGSEGV (invalid r9 and r10 values)
but those values seems strange versus related disassembly code.
* I would need help from there.
