Yes, I can provide a test case, but unfortunately it is not minimal. As
I was not able to find the faulty location and/or combination of cairo
operations, you will need to get a copy of GenomeTools. I have prepared
a test case in the 'for_aj' branch of
You can build genometools by simply using 'make', append '64bit=yes' to
build for a 64bit system.
An example call of the problematic tool can be found in cairo_error_run.sh.
I have also attached a valgrind session with line numbers present, I
have also looked at the respective positions in the cairo code
(_cairo_pdf_operators_emit_glyph) but am not familiar enough with the
environment there to be of much help. I do not see how I could be
manipulating the cairo_glyph_t's there...
Thanks in advance,
