[Octave-bug-tracker] [bug #57353] crash signal 11 when using patch() with large stl file

[Hg200]

Follow-up Comment #19, bug #57353 (project octave):

Here is my backtrace output. Some informations in advance:

RAM is 4GB total

(gdb) break graphics.cc:10125
Breakpoint 1 at 0x7fcab33c56e5: file libinterp/corefcn/graphics.cc, line
10125.
(gdb) c
Continuing.
Thread 5 "QThread" hit Breakpoint 1, patch::properties::update_vertex_normals
(this=0x7fca88379650, reset=false, force=false)
    at libinterp/corefcn/graphics.cc:10125
10125         std::vector<RowVector> vec_vn [num_v];  // list of normals for
vertices
(gdb) print num_v
$1 = 471129
(gdb) ptype num_v
type = long

Looks not suspicious (?) because is consistent with the call to patch (i am
calling with 3 x 157043 = 471129 points). Hint: I am using different stl data
(much smaller) than marcel.

Backtrace:

Thread 5 "QThread" received signal SIGSEGV, Segmentation fault.
