Segmentation fault in parse_png_file() about astc-encoder

[EnchantedJohn]

so I use the command is
/home/lx/coverage/testapp/astc/HFL/astcenc -c xxx.png test.astc 6x6 -medium

then there is gdb information:

Program received signal SIGSEGV, Segmentation fault.

No means to reproduce this specific issue without the test file to verify that this is fixed, but the upgrade to the new stb_image library in PR #48 solves many cases of corrupt images causing problems.

Closing, as cannot reproduce.
