Hello,

You’re right about --verbosity=4 interrupting builds, I get:

--8<---------------cut here---------------start------------->8---
$ guix build --verbosity=4 vim --no-substitutes

IOW, the debugging message is interpreted as an error message.

Indeed, if we strace it, we see:

--8<---------------cut here---------------start------------->8---
read(13, "gmlo\0\0\0\0", 8)             = 8
read(13, "_\0\0\0\0\0\0\0", 8)          = 8
read(13, "|   building of `/gnu/store/ld1kzfb1jyh0jw6yxhprcd3zvj57c986-vim-8.0.1428.drv': goal destroyed\n", 95) = 95
read(13, "\0", 1)                       = 1
write(2, "|   building of `/gnu/store/ld1kzfb1jyh0jw6yxhprcd3zvj57c986-vim-8.0.1428.drv': goal destroyed\n", 95) = 95
read(13, "ptxc\0\0\0\0", 8)             = 8
read(13, "w\0\0\0\0\0\0\0", 8)          = 8
read(13, "|   |   |   bind mounting `/dev/full' to `/gnu/store/ld1kzfb1jyh0jw6yxhprcd3zvj57c986-vim-8.0.1428.drv.chr--8<---------------cut here---------------end--------------->8---

Normal messages arrive with the “gmlo” prefix, but the “bind mounting”
message arrives with the “ptxc” prefix, which (guix store) interprets as
‘%stderr-error’ and raises an exception right away.

Not sure why we get that “ptxc” prefix.
