Dmitri,

Why don't you file a bug report so you can attach these long logs.

​I will.

Also, I built a version of Octave with the address sanitizer enabled and
then ran

run-octave -f --no-gui-libs --eval 'exit' | & tee leak.base.log
run-octave -f --no-gui-libs --eval 'graphics_toolkit gnuplot; plot (1:3);
exit' | & tee leak.gnuplot.log

The results were

SUMMARY: AddressSanitizer: 204896 byte(s) leaked in 3198 allocation(s).
SUMMARY: AddressSanitizer: 205184 byte(s) leaked in 3200 allocation(s).

​I have seen those as well. ​

 

So there does seem to be a problem.

​Some (most) of them are warnings, but some are errors which result in program

being aborted. E.g. i cannot really run "make check" since it dies on the very first test.​

​Many (most | all ?) of them comes with a
<<<
​HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext
      (longjmp and C++ exceptions *are* supported)
>>>

​Any chance it could be the case?​
