[SOLVED] Why "EWA Quadratic" becomes "EWA Quddratic"?

[NicolasRobidoux]

Here is another script that produces, this time, four mispellings (Lanczos3Sarrpest, Rbiidoux, Tiaangle, and Quddratic). None of my various installs (oldest is 6.7.9-9 from yesterday's tar, so they all are fairly recent) has managed to get this right. (I realize that this does not happen with most people's installs, but a private email from Anthony suggests that it's not only my installs.)

There definitely is a pattern: Drop the second letter after a capital letter, and duplicate the fourth one (which has become the third one). But not always.

[NicolasRobidoux]

It's not OpenMP: No difference if I configure with --disable-openmp.

We can reproduce the problem you posted and have a patch in ImageMagick 6.7.9-10 Beta, available sometime tomorrow. Thanks.

[NicolasRobidoux]

Cristy's fix of montage.c and/or miff.c in svn rev 9507 fixed this. \o/

[henrywho]

There are still many spelling errors in http://www.imagemagick.org/Usage/resize ... linear.png

[NicolasRobidoux]

@Henry:
I expect (hope?) the misspellings will disappear when the IM used to automatically generate the site catches up with the bug fixes.
Thank you for pointing it out.

[henrywho]

Similar stuff for me.... I am now struggling with GCC 4.7.2 Mingw64's link-time-optimization (-flto) .... It gives weird linking error (it said a BZ2 decompression routine was declared as a variable but then re-defined as a function). No such error before I added -flto....

Oh. Okay, perhaps it was not the filename length.
