Subject: libgraphicsmagick: please provide debug symbols

Package: libgraphicsmagick-q16-3
Version: 1.3.23-2
Severity: wishlist
Dear Maintainer,
Please provide debug sybols for the library.
Due to the sigsegv hook it installs (completely non-thread-safely!),
i need to find a way to workaround it, and i needed debug symbols
to catch it first...

Did you try graphicsmagick-dbg meanwhile? It may help alone.

Oh well :)
I did try it, but for some reason it was not picked up by gdb, so i
reported this issue.
But now i have retried it, and it worked
(along with mkdir /build && cd /build && apt-get source tiff &&
apt-get source graphicsmagick)
On an unrelated note, it does not seem to have helped to solve my
issue with graphicsmagick
setting their own error/warning handlers :(
ReadTIFFImage() does call
TIFFSetErrorHandler()/TIFFSetWarningHandler() to set it's own
handlers, but then does not restore the original ones after it is done.
And anyway since apparently those handlers is global per-program, it
would never work.
So broken :(
This causes numerous crashes of darktable (we use libtiff and gm side-by-side).
So i suppose this bug can be closed...
