调研方向

使用 Julia 1.7、MKL 0.4.2、PyPlot 2.10.0 和 PyCall 1.92.5 重现两个导入顺序示例。从 src/PyPlot.jl 中 tight_layout 附近（第 174-177 行）开始，并跟踪 trace 中显示的 PyCall 调用。当在 PyPlot 之前加载 MKL 时 tight_layout 不再发生段错误，且报告的行为仍由回归测试覆盖时，即表示完成。

由索引模型根据 Issue 内容生成。

描述

This gives a segfault:

using MKL
using PyPlot
fig = PyPlot.figure()
plot(rand(10), rand(10))
tight_layout()

signal (11): Segmentation fault

But this doesn't (MKL is used after PyPlot):

using PyPlot
using MKL
fig = PyPlot.figure()
plot(rand(10), rand(10))
