Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

Compiling octave with jemalloc (from homebrew) causes an octave-svgconvert utility to crash with some minimal coredump:

(lldb) run
Process 34787 launched: '/Users/dmitri/src/octave/out_gopt/src/octave-svgconvert' (arm64)
Process 34787 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x6478)

Replacing the homebrew's jemalloc with a self-compiled version from git

% git rev-parse HEAD
3688dfb5c3b7d94a12e18b753c0fc9c405b77b1f

solves the problem.

What happened (include all command output)?

program crashes

What did you expect to happen?

program does not crash

Step-by-step reproduction instructions (by running brew commands)

compile octave with jemalloc (set `LIBS='-ljemalloc'`) 
For some existing SVG file (say `tx.svg`) run from the build directory

./src/octave-svgconvert "tx.svg" pdf 100 "../etc/fonts/FreeSans.otf" 0 "t1.pdf"

[Bo98]

We use the latest stable release of jemalloc: 5.3.0. If it has been fixed upstream then we'd need to find which commit did it and consider if it's safe to backport. We won't be just taking the latest unstable HEAD.

They have tested commits
jemalloc/jemalloc#2060
I am personally fine with a self-compiled version. The bug report is just FYI.
