Segmentation Fault When Writing to Bins #18

Closed Etang21 closed 3 years ago

Etang21 commented 5 years ago

Description Settingbins=true in compute_flow.cpp, rebuilding, and running compute_flow results a Segmentation fault. This appears to be due to an incorrect initialization of the fx file descriptor in compute_flow.cpp:263, resulting in a write to a NULL file descriptor.

Fix Fixing the initialization on compute_flow.cpp:263 fixes the issue. @pedro-abreu, this bug appears to have been introduced in b57b69a837a97e6688a9fc3ce8a128e23cc031c1. I'll submit a pull-request momentarily!
