Sharp: invalid next size (fast) - ARMv7 - Raspbian GNU/Linux 9 (stretch)

[jim-fx]

Hi,
I'm having an error with sharp on my raspberry pi, the same code works flawlessly with the same sharp version on my macbook. Here's the error:

*** Error in '/usr/local/bin/node': free(): invalid next size (fast): 0x71700dd8 ***

And heres the code:

//CREATE PLACEHOLDER IMAGE
sharp(fileUrl)
    .rotate()
    .resize(pDimension.width, pDimension.height)
    .jpeg({
        progressive: true,
        quality: 20,
        optimiseScans: true
    })
    .blur(2)
    .toFile(imageDirectory + "/" + imageName + "_p" + imageExt)
    .then(function () {
        finished();
    })
    .catch(err => console.log("Resize Err: "+err));

I have tried installing sharp without preinstalling libvips and then installing sharp with preinstall libvips and --sharpcxx11=1. Then i have tried to change _GLIBCXX_USE_CXX11_ABI=1 in binding.gyp with npm rebuild. Also i have tried node version 9, 10.0.0, 10.8.0 and 10.9.0.

Edit2: npm rebuild not reinstall

Hello, did you see #1336? This definitely looks like a mismatch in the value of _GLIBCXX_USE_CXX11_ABI between libvips and sharp.

[jim-fx]

Yes, i went trough the steps described in that issue, so i changed _GLIBCXX_USE_CXX11_ABI=0 to _GLIBCXX_USE_CXX11_ABI=1 in binding.gyp and than called npm rebuildbut the error still persisted. Was that correct, or what exactly do you mean by "mismatch".

Thank you for the help,
Cheers, Max

Edit: spelling

[lovell]

The pre-compiled libvips v8.6.1 for ARMv7 was erroneously compiled without setting _GLIBCXX_USE_CXX11_ABI and the compiler assigned an implicit value of 1 but sharp assumes these will be 0.

To work around this until sharp v0.21.0 is out, re-compiling sharp with an explicit 1 value should fix this (as it did with #1336). It sounds like you did the right thing so I'm a little surprised there's still a problem. Did you change line 120 (assuming sharp v0.20.7)? https://github.com/lovell/sharp/blob/v0.20.7/binding.gyp#L120

[jim-fx]

I think i found the problem, i changed the line above where it says:
'_GLIBCXX_USE_CXX11_ABI=<!(if readelf -Ws "$(PKG_CONFIG_PATH="<(pkg_config_path)" pkg-config --variable libdir vips-cpp)/libvips-cpp.so" | c++filt

To:
'_GLIBCXX_USE_CXX11_ABI=1#<!(if readelf -Ws "$(PKG_CONFIG_PATH="<(pkg_config_path)" pkg-config --variable libdir vips-cpp)/libvips-cpp.so" | c++filt

So it was (as usually) a human error. I can't test right now but i will report as soon as i get home.

I'm very thankful for your help and your amazing library.

Cheers, Max

Okay, it worked!
