I created a custom SOP. Sometimes I can cook it successfully, other times it segfaults. It seems to always segfault after the “cookMySop()” function completes (i.e., outside of the code that I wrote???). When it segfaults, it either gives me one of two error logs, or no error log at all.

Here are the two error logs. Can anyone make sense of them and direct me in a direction that I can start to look to debug this?

A mozesz sie kodem podzielic? Latwiej bedzie zdiagnozowac pacjenta

Raczej nie, moj kod ma okolo 1600 linii…
Proboje uzywac valgrind.

Mialem przypadek gdy caly kod z metody Cook() dzialal dobrze ale podczas ladowania Houdego wyskakiwal mi blad o nieodpowiednim tagu w “$HOME\houdini13.0\config\Dialogs\”. Chyba tam jakas informacja o UI jest tworzona.

Nie pomagala ponowna recompilacja ani wykasowanie katalogu $HOME aby Houdy przetworzyl dane jeszcze raz. Zrobilem nowe pliki i dokladnie ten sam kod linijka po linijce napisalem i poszlo . Do tej pory nie wiem co bylo powodem.
