Subject: pahole v1.18 introduced a bug that hangs a product-line build
Date: Fri, 24 Nov 2023 10:23:42 -0500 [thread overview]

Hello,
We have a product build that hangs at the same place every time because of
a change introduced in pahole.c v1.18. The hang occurs in all versions of
pahole.c since, including the latest. We are using Ubuntu 22.04.3 for
builds.
The attached file
"modified-v1.17-pahole.c-that-works-with-dwarves-v1.18-and-EMCMFirmware-builds_Nov-22-2023-04.tar.bz2"
contains pahole.c v1.17 that has been merged with as many pahole.c v1.18
changes as I could so far and still successfully build our product.
If you diff between that modified v1.17 pahole.c and a pristine unchanged
v1.18 pahole.c file, the bug introduction is somewhere in that difference.
I have attached the file "pahole.c-v1.18-pristine-original-unchanged.rar"
for convenience.
Please help me find the root cause of this hang and a fix for pahole or a
workaround for all future versions of pahole.
Thank you!
Joe
