[Octave-bug-tracker] [bug #47914] segfault with OpenGL patches and address sanitizer

[Dmitri A. Sergatskov]

Follow-up Comment #11, bug #47914 (project octave):


changeset:   22099:4c0f78b3c86f

I cannot complete the doc build if I compile with -fsanitize=address ; there
are too many leaks building voronoi.txt.
It gives up with 
SUMMARY: AddressSanitizer: 126332 byte(s) leaked in 2675 allocation(s).
Makefile:27702: recipe for target 'doc/interpreter/voronoi.txt' failed

(I had to set  ASAN_OPTIONS=new_delete_type_mismatch=0 or I get
SUMMARY: AddressSanitizer: new-delete-type-mismatch
(/lib64/libasan.so.3+0xc8b60) in operator delete(void*, unsigned long)
)

I could run 
ASAN_OPTIONS=new_delete_type_mismatch=0 ./run-octave --no-gui
and execute 'demo patch 2" w/ no problem after that)

This is on ccomputer with nvidia card:
