I'm trying to compile a vhdl file using xilinx's fuse (part of ISE) using a library I got from my university - pgm_pkg.vhd. The library is used to read the *.pgm image format into vhdl simulator. It works ok when simulated in Modelsim at windows, but unfortunately while compiling on debian using fuse it produces the following error:
*** glibc detected *** /opt/Xilinx/14.4/ISE_DS/ISE/bin/lin64/unwrapped/fuse: malloc(): memory corruption (fast): 0x00000000019c7780 ***
Using Modelsim (which is soo slow in student version) at virtual machine running windows (which makes it even slower) is something I would like to avoid at any cost.
I've narrowed the problem down to the function read_pgm_file() which iterates over the *.pgm file and provides the subsequent pixels of the image.
I've read that this kind of error is raised by gcc often many lines before the compilation crushes, but even that isn't helpful as fuse is a closed-source application. I've tried using different *.pgm pictures, I've also tried to compile it using verbose mode (I didn't find there anything helpful) and with the compilation multithreading off - still the same error occurs.
1) How do I handle such an error? Are there any tools for debugging during compilation? 2) What's wrong with the library? I can't see anything that could cause problems, especially that the same library works on windows very well.

PGM is an ASCII-based format, which is as well because ISE Simulator has issues accessing binary files. (It can be done, but you have to jump through a few hoops, including a 9-byte header that Xilinx actually refuse to document)
The most likely cause is that you are attempting to return a fixed size 640x640x4 byte array on the stack, regardless of the actual image size. Whoever wrote that package needs their head examined.
But before going further along this line of reasoning, it is worth checking that a much smaller array on the stack will work. Find a small PGMfile (say, 16*16) and edit the package for a "max" slightly larger than the file (20*20 or 32*32 should be safe).
Assuming that works, report back and we can work out a more appropriate solution : either a procedure with an OUT parameter (caller allocates it) or a function returning an access type (pointer) to the actual storage.
Alternatively : try GHDL as an alternative simulator. It has runtime options to control the stack size, which may bypass the problem.
EDIT following some experimentation: (1) The "memory corruption" appears to arise on lines containing white space after the data. Deleting that in a text editor removes that issue (rewriting the line parser to eliminate that problem is probably a better answer...)
(2) After fixing that, the elaboration stage appears to hang.
A few asserts after the line pgm.pixel(pi,pj) := number; reveal that it IS actually running; crawling or slithering might be a better term. I haven't actually summed up the patience to let it run beyond line 100 so I can't say if the result is successful.
pgm.pixel(pi,pj) := number;
assert pi < 10 report "Pixel " & natural'image(pi) & " : " & natural'image(pj) severity note;
(etc)
EDIT following further digging:
Apparently ISIM treats elaboration differently from runtime computation; assuming that little or no actual work is done there, and its elaboration is neither to the same quality nor performance as the executable operating at simulation time.
So replacing the architecture with:
architecture behavioral of test_raw_tb is
--constant infile : pgm_record_type := read_pgm_file(ifile);
begin -- architecture
process
variable infile : pgm_record_type;
begin
infile := read_pgm_file(ifile);
wait;
end process;
end behavioral;
as one way of forcing the file parsing to be deferred until runtime; compilation succeeds, and simulation proceeds at a satisfactory speed until:
ERROR: Index 640 out of bound 0 to 639.
ERROR: In process test_raw_tb.vhd:17
(this error does not occur with the whitespace fixed file, so there still seems to be a parser issue to address)
