[BUG] [GR] EXCEPTION_ACCESS_VIOLATION in libGR.dll

[inkydragon]

Details

The following code crashed julia:
Since the error occurs in libGR, it appears to be an error in the GR backend rather than in julia.

xref: JuliaLang/julia#55883

using Plots

f(x, y) = x + y
x = range(0.93, 0.94, length=500)

p = contour(x, x, f; clabels=true)
display(p)

# p = contour(x, x, (x, y) -> x^2 + y^2; clabels=true)
# display(p)

[t-bltg]

If this error is GR related and can be (preferably) isolated to plain GR commands, it should be reported upstream to https://github.com/jheinen/GR.jl.

This seems a windows only issue.

[inkydragon]

Yes this is a GR only issue.

using GR

f(x, y) = x + y
x = range(0.93, 0.94, length=500)

p = contour(x, x, f; clabels=true)  # <- crash
