Segmentation fault for specific pdf on alpine linux docker container #1287

Hi, this looks like a stack overflow inside libpoppler's recursive |
|
Thanks @lovell ! The requirement is for alpine linux, I will check for the same file on Ubuntu and update the results here. |

I agree with Lovell, this looks like a stack overflow. Alpine uses musl for its libc, rather than the glibc that's usual on Linux. glibc typically gives threads >2MB of stack, but musl only allows 80kb, more than 20x smaller: https://wiki.musl-libc.org/functional-differences-from-glibc.html#Thread-stack-size Unfortunately, this means you can't really run code which does any significant amount of recursion on Alpine. We've tried to keep libvips stack usage down, but of course we can't control the code in libraries which libvips uses, like poppler. |

I think this is done in master, I'll close. |

@priyankatapar Can you please edit your issue and remove links to issues from 1 to 589? It's confusing. You probably need to use a different quote. |

@wkuranowski OK, edited. |
Hello,
We are facing seg fault while processing a specific pdf file with Vips 8.7.4 version.
Click for the stack trace.
Anyone faced similar issue and did they find solution for this?
Thanks!
