[Octave-bug-tracker] [bug #47840] exec segfaults on Windows

[Tatsuro MATSUOKA]

Follow-up Comment #4, bug #47840 (project octave):

I have execute octave-4.0.2 self built on windows.
(http://octave.1599824.n4.nabble.com/Octave-build-on-windows-using-octave-binary-itself-td4676652.html)


I ran ./run-octave -g --no-gui


(gdb) break oct-syscalls.cc:77
No source file named oct-syscalls.cc.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (oct-syscalls.cc:77) pending.

No stack.


At the moment, I could not get useful information.
In addition, I failed to set break point at octave_syscalls::execvp on gdb.
Perhaps this is my mistake to set a break point.
