Thanks!\r\n\r\n-->\r\n\r\n## What's the problem (or question)?\r\nARMv7 binaries compressed with UPX 3.95 --ultra-brute give no output or segfault. \r\nTested using hellworld C program. The arm upx binary from the \"Releases\" page on this project doesn't run either until it is decompressed.\r\n<!--- If describing a bug, tell us what happens instead of the expected behavior -->\r\n<!--- If suggesting a change/improvement, explain the difference from current behavior -->\r\n\r\n## What should have happened?\r\nupx --ultra-brute ./binary ---> profit\r\n<!--- If you're describing a bug, tell us what should happen -->\r\n<!--- If you're suggesting a change/improvement, tell us how it should work -->\r\n\r\n## Do you have an idea for a solution?\r\nNo\r\n<!--- Not obligatory, but suggest a fix/reason for the bug, -->\r\n<!--- or ideas how to implement the addition or change -->\r\n\r\n## How can we reproduce the issue?\r\n<!--- Provide unambiguous set of steps to reproduce this bug. Include code to reproduce, if relevant -->\r\nI compile upx myself (with ucl). The resulting binaries that it then compresses won't run. \r\nI _then_ downloaded the arm version provided from this project, and the binary itself doesn't run either as it is compressed with UPX 3.95. After decompressing the binary it then functions, but it still creates unusable binaries.\r\n\r\n## Please tell us details about your environment.\r\n<!--- Include as many relevant details about the environment you experienced the bug in -->\r\nNetgear R7000 router\r\n\r\nroot@R7000:~# upx --version\r\nupx 3.95\r\nUCL data compression library 1.03\r\nzlib data compression library 1.2.11\r\nLZMA SDK version 4.43\r\n\r\nroot@R7000:~# cat /proc/cpuinfo\r\nProcessor       : ARMv7 Processor rev 0 (v7l)\r\nprocessor       : 0\r\nBogoMIPS        : 1998.84\r\nprocessor       : 1\r\nBogoMIPS        : 1998.84\r\nFeatures        : swp half thumb fastmult edsp\r\nCPU implementer : 0x41\r\nCPU architecture: 7\r\nCPU variant     : 0x3\r\nCPU part        : 0xc09\r\nCPU revision    : 0\r\nHardware        : Northstar Prototype\r\nRevision        : 0000\r\nSerial          : 0000000000000000"}}
