I had a different comment in the first line in the file. Unfortunately either I do not understand the problem, or I can not reproduce unexpected behaviour. I tried to "redo f.do", where f.do is executable file with missing shebangs, shebangs leading to unexistent files, with failing programs, and redo gives an ordinary error and bad return code. Can you describe the problem more? -- Sergey Matveev (http://www.stargrave.org/) OpenPGP: CF60 E89A 5923 1E76 E263 6422 AE1A 8109 E498 57EF [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 833 bytes --] ^ permalink raw reply [flat|nested] 4+ messages in thread

For my MWE, I also see a proper error message. I can, however reproduce the error with a particular file in a particular project. This is the message: ``` err nandnor/genexp: fork/exec /home/mraitza/docs/phd/diss/exps/nandnor/genexp.do: exec format error panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x52266c] goroutine 19 [running]: main.runScript.func5.1(0xc00011c000, 0xa6, 0xc00009e12b, 0xc0000be098, 0xc0000be0b0, 0xc0000be0c8, 0xc0000d8600, 0x2e, 0x7fff8d73a8cd, 0x6, ...) go.cypherpunks.ru/goredo/run.go:459 +0x1ec main.runScript.func5(0xc00011c000, 0xa6, 0xc000118000, 0xc0000ba3a0, 0xc0000c26c0, 0xc0000f4f00, 0x3e, 0xc0000be0b0, 0xc00009e590, 0xc0000c0600, ...) go.cypherpunks.ru/goredo/run.go:542 +0xdd3 created by main.runScript go.cypherpunks.ru/goredo/run.go:403 +0x1db2 ``` And the offending file genexp.do: ``` # [[file:nandnor.org::+begin_src shell :tangle genexp.do :tangle-mode (identity #o755) :shebang "#!/bin/sh"][No heading:2]] #!/bin/sh d=../basiccmos/wcd mkdir -p "$d" cp 3nandnor.py "$d" redo "$d"/4.inputs.props ln -sf 4.inputs.props "$d"/3nandnor.props cp ../4inputs-ndet-power-template.net "$d"/3nandnor.template.net # No heading:2 ends here ``` So it may have to do with path lengths and such things. Copying the file to some other place already destroyed the effect. ^ permalink raw reply [flat|nested] 4+ messages in thread

It happens when stderr saving is active (-k, REDO_LOGS=1). Will fix in the following release.
