What steps will reproduce the problem?
jpge::params params;
params.m_quality = 95;
params.m_subsampling = jpge::H2V1;
compress_image_to_jpeg_file("test.jpg", width, height, 3, image, params);
What is the expected output? What do you see instead?
Expect to write test.jpg. Writes the file correctly but crashes.
Program received signal SIGABRT, Aborted.

What version of the product are you using? On what operating system?
jpge 1.03, Ubuntu 11.10
Please provide any additional information below.
If I edit the cfile_stream.close() method in jpge.cpp by inserting
m_pFile = NULL; //Prevent double close
at line 928 it works fine.

What steps will reproduce the problem?
1. Only happens in the Nexus 4 device. (Android 4.3)
2. When taking a JPEG picture, the JPEG data is passed for decompression into
the method: decompress_jpeg_image_from_memory method
What is the expected output? What do you see instead?
Decoding fails. Debugging the library I've found that the error code is
"JPGD_UNEXPECTED_MARKER", and the marker itself that seems to make it fail is
"M_RST7"

jpgd.cpp, line 3101 should be:
if (((req_comps == 1) && (decoder.get_num_components() == 1)) || ((req_comps ==
3) && (decoder.get_num_components() == 3)))

Here is a patch to reduce dynamic memory allocations:

It is described here:

Not very well tested, but it might be useful.
