Description

Using OCCT 7.5.2 with the patch for #0029645 and #0031147

When trying to build a pipe with the provided spine, profiles and .tcl file I get a crash in C++ and in DRAW, with the following error in DRAW:

An exception was caught 0x558e4af91d40 : OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 38

I am using "DT_ShapeDivide" on the spine, "setsweep -DT" and "buildsweep r -C -S".
