Segmentation Fault when calling sync_post in api.cpp

[wyzd03105]

Hi The stack trace is as below. Is there any clue to drill down to the cause of the problem? P.S. The error does not happen each time the sync_post API get called. ` Program terminated with signal 11, Segmentation fault.

as you can see, binapi doesn't provide binapi::rest::api::future_new_order: https://github.com/niXman/binapi/blob/master/include/binapi/api.hpp

[wyzd03105]

Yes. But it will call sync_post at the lower level. Future_new_order is my newly added function. I think the problem might lie at the lower level.

[niXman]

then why the problem occurs only with the function you added? ;)

please close.

OK.But I'll take further investigation on this issue.
