Hey everyone,
I'm using some 3rd party code that depends on zlib. In particular, it uses gzread() in order to read a file. Unfortunately, the corresponding piece of code causes a segfault in ld.lib.so.
I narrowed this down to the following minimum example:
gzFile gzfile_components = gzopen("test.txt", "rb"); unsigned char buffer[1024*1024]; gzread(gzfile_components, buffer, sizeof(buffer));
As you can see, the buffer is quite large but this the actual (and reasonable) value used in the 3rd party code. As soon as I reduce the size to e.g. 4096, the segfault is gone.
The file I used has a size of 293 bytes. I'm using base-linux. I also remember using this code successfully on a different computer with an older version of Genode (14.03).
Any ideas/comments on this?
