nanogui: Thread: png strange issue

Good morning,
  I have a problem to load png when nano-X is compiled with
FreeType 1.x:


####################################################################
# TrueType font support thru FreeType 1.x
####################################################################
HAVE_FREETYPE_SUPPORT    = Y
INCFTLIB                 = /usr/include/freetype1
LIBFTLIB                 = /usr/lib/libttf.so
FREETYPE_FONT_DIR        = "fonts/truetype"

-- 


####################################################################
# PNG support via libpng and libz
####################################################################
HAVE_PNG_SUPPORT         = Y
INCPNG                   = .
LIBPNG                   = /usr/lib/libpng.a
LIBZ                     = /usr/lib/libz.a

while if compile HAVE_FREETYPE_SUPPORT    = N the png load correctly.

the problem is in this static int
ReadBlock(void *b, int n) but I think that i see the effect and not a
cause.

Thanks

This is truly a strange problem.  Why is it you think the problem
is in ReadBlock, and which file is that in?

Thank you Greg,
the ReadBlock is a point where I receive a Segmentation Fault to nanox,
and file is in src/nanox/client.c, I made a debug with printf cause
I have a tiny dev. enviroment, and when nanox call
GrLoadImageFromFile --> TypedReadBlock --> ReadBlock --> read
return 0 and a client exit.

Thank you very much

We need a stack trace on the nano-X codefile, not the
client application, which is hanging in ReadBlock/read.
When nano-X core dumps, the client gets EOF (return 0)
and exits normally.
