signal_tools.bsh:trap_chain

[scott-vsi]

If I run make_temp_path TMP_DIR in a just target, this line causes a trap when run via just.

vsi_common/linux/signal_tools.bsh

Line 75 in aec3ddc

last_info="$(trap '' "${2}"; trap -p "${2}" | { read x ; echo "${x##* }"; })"

Adding set -xv right before that line produces this

trap '' "${2}"; trap -p "${2}" | { read x ; echo "${x##* }"; }
++ trap '' EXIT
++ trap -p EXIT
++ read x
print_error "${BASH_SOURCE[0]}" "${LINENO}"
+++ print_error /Users/sgrichar/terra/external/vsi_common/linux/signal_tools.bsh 76

The fix (66291fe) is simple, although why that fixes the problem is not clear:

-    last_info="$(trap '' "${2}"; trap -p "${2}" | { read x ; echo "${x##* }"; })"
+    last_info="$((trap '' "${2}"; trap -p "${2}") | { read x ; echo "${x##* }"; })"
