Failing test - db.lua

[Pavel Durov]

Issue

Error on running db.lua test with both serial and non-serial compilation:

$ YKD_SERIALISE_COMPILATION=1 ../src/lua -e"_U=true" db.lua 
testing debug library and debug information
+
testing inspection of parameters/returned values
+
+
testing traceback sizes
testing debug functions on chunk without debug info
OK
mremap_chunk(): invalid pointer
Aborted (core dumped)

$ YKD_SERIALISE_COMPILATION=0 ../src/lua -e"_U=true" db.lua 
testing debug library and debug information
+
testing inspection of parameters/returned values
+
+
testing traceback sizes
testing debug functions on chunk without debug info
OK
Segmentation fault (core dumped)

Notes

Both compilation modes are non-deterministic - sometimes it errors out and sometimes completes successfully.
When debugging with gdb, it runs successfully.

YkLua - yk-location-allocation/056cf6ae7cb3ebd59a7e0dc89df99c03f0e8d3d9
