'Cannot allocate memory' when exporting mesh #259
Description
System information
SolveSpace version: 3.0~33b6e517 (current master, built with clang 4.0)
Operating system: Arch Linux x86-64
Expected behavior
Solvespace should have reported an error (since I'm pretty certain the model has issues that lead to a somewhat broken mesh) or it should successfully export the mesh.
Actual behavior
Solvespace hangs for a while, then crashes with a failed 'Cannot allocate memory' assertion.
Additional information
File ../../src/platform/unixutil.cpp, line 105, function MemAlloc:
Assertion 'Cannot allocate memory' failed: ((p != NULL) == false).
