Please provide more info. Is this a custom build, what platform, etc. If it's a custom or distro build, please rebuild with debug symbols and get a backtrace + valgrind output. There is no general issue AFAIK, I run the latest every day, and this is the first report I see.

Both reports crashed in your libc (!!), not in Fifth or any library in my control, though your valgrind was too old to be useful. Can you update valgrind and try it again?

valgrind-3.11.0.txt

Can you also reproduce in the webkitfltk testapp?

[clbr]

Oh, and what is your libpng version? For the jumpbuf to be NULL, libpng init would have failed. That's not supposed to be possible.

[clbr]

In your valgrind output I see two versions:
/usr/lib64/libpng17.so.17.0.0
/usr/lib64/libpng16.so.16.16.0

That could cause this crash. Why do you have two versions of libpng linked at the same time?

[szukw000]

Why do you have two versions of libpng linked at the same time?

I do not know WHY. I only use LIBPNG17. My SLACKWARE distribution installed
LIBPNG14 and LIBPNG16.

fifth-0.4/Makefile:

CXXFLAGS = -g -O2 -I/usr/include/libpng16 -I/usr/include/libpng17

An the Makefile.am contains the lines (20-22):

cp /usr/lib/{libssl,libcrypto}*.so.1.* $(BASE); \
cp /usr/lib/{libcurl,libpng12,libphysfs,libcares,librtmp}*.so.? $(BASE); \
cp /usr/lib/libjpeg*.so.?? $(BASE); \

Makefile.in the lines 879-881:

cp /usr/lib/{libssl,libcrypto}*.so.1.* $(BASE); \
cp /usr/lib/{libcurl,libpng12,libphysfs,libcares,librtmp}*.so.? $(BASE); \
cp /usr/lib/libjpeg*.so.?? $(BASE); \

All libraries on my 64-Bit machine are in '/usr/lib64' and '/usr/local/lib64'.

It would really be advisable to only have one. If you want to use 1.7,
then you need to remove the headers and symlinks of 1.6, so only 1.7
can be used by new programs. But how to do that is Slackware-specific,
I wouldn't know.

-I/usr/include/libpng16 -I/usr/include/libpng17

This is wrong. Only one should be present.

An the Makefile.am contains the lines (20-22):

cp /usr/lib/{libssl,libcrypto}*.so.1.* $(BASE); \
cp /usr/lib/{libcurl,libpng12,libphysfs,libcares,librtmp}*.so.? $(BASE); \
cp /usr/lib/libjpeg*.so.?? $(BASE); \

These are for my use (the precompiled binary package), so you can
ignore them.
