Investigated further using valgrind with the debug package. Problem seems to be with ImageMagick. There is a crash happening at RelinquishMagickMemory (memory.c:589) when free(memory) is called. Here is the valgrind output: ========================================== gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g573x489 "-sOutputFile=/tmp/magick-XXCt7OBg" "-f/tmp/magick-XXspO88W" "-f/tmp/magick-XXi7GxND" ==30776== Invalid free() / delete / delete[] ==30776== at 0x4A0560B: free (vg_replace_malloc.c:233) ==30776== by 0x4D11F0D: RelinquishMagickMemory (memory.c:589) ==30776== by 0x6AA650B: png_IM_free (png.c:1435) ==30776== by 0x5BEEABB: png_free_data (png.c:490) ==30776== by 0x3B3C4051EB: (within /usr/lib64/libpng12.so.0.22.0) ==30776== by 0x3B3C411790: (within /usr/lib64/libpng12.so.0.22.0) ==30776== by 0x3B3C411AD3: png_destroy_read_struct (in /usr/lib64/libpng12.so.0.22.0) ==30776== by 0x6AAAE51: ReadOnePNGImage (png.c:1717) ==30776== by 0x6AB291D: ReadPNGImage (png.c:2834) ==30776== by 0x4CA1F4F: ReadImage (constitute.c:386) ==30776== by 0x570CEBF: ReadPSImage (ps.c:706) ==30776== by 0x4CA1F4F: ReadImage (constitute.c:386) ==30776== Address 0xF4240 is not stack'd, malloc'd or (recently) free'd =========================================== That command line runs fine with just using ghostscript. -- Prof. S.
